Apollo 11 - 46th anniversary

 

tmpAA45

Sadly, no one is talking about this.

 

 

 

Twelve of these astronauts walked on the Moon's surface, and six of those drove Lunar Roving Vehicles on the Moon. While three astronauts flew to the Moon twice, none of them landed on the Moon more than once. The nine Apollo missions to the Moon occurred between December 1968 and December 1972.

 

 

Forty six years ago today, Neil Armstrong and Buzz Aldrin became the first two people to walk on the Moon, and Armstrong snapped this iconic photo of Aldrin (and of himself, too—that tiny little astronaut reflected in the visor is Armstrong). But it wasn’t until today that Aldrin finally gave it the perfect caption.

Strange facts:

 

1.You would expect that when NASA asks you to be the first man to walk on the Moon that they would consider the possibility of things going wrong. Well for Neil Armstrong he couldn’t afford the life insurance policy for an astronaut. However, along with Michael Collins and Buzz Aldrin he wasn’t alone. All three astronauts of the Apollo 11 mission decided to create a plan of their own to support their families if something bad was to happen. Before the Apollo 11 mission in July 1969 when all three astronauts were in pre-launch quarantine, they signed hundred of autographs and sent them to a friend. If anything was to happen to the astronauts during their mission, the entrusted friend was to send the autographed memorabilia to each of the astronaut’s families. This way they could make some money by selling the signatures of the Apollo 11 crew.

2. One thing that surprised the astronauts who visited the Moon was the strong odour of the lunar dust which they were only able to smell when they got back inside the Lunar Module. While conducting experiments on the surface of the Moon the astronauts’ spacesuits gathered the moon dust in the creases of the suit, once the crew returned to the LM and removed their helmets the dust got everywhere even on their hands and faces (some astronauts even tasted it). After coming into contact with oxygen for the first time inside the Lunar Module, the four billion years old moon dust produced a pungent smell. As most of the astronauts had a military history they could compare the aroma to that of gun powder. Neil Armstrong described the dust’s scent as similar to to wet ashes in a fireplace. This distinct smell remains a mystery as moon dust and gun powder have no similar compounds and the exact explanation remains unknown.

3. There’s no doubt that the people behind the Moon missions were smart and skilled. The kind of expertise required seems beyond our general understanding. The spacesuits that the astronauts wore in the Apollo 11 missions were made by little old ladies, a bit like the ones in the Shreddies advert. NASA approached the International Latex Corporation (ILC) to produce a suit alongside the aerospace company Hamilton Standard. However Hamilton Standard became wary of the ILC and designed their own suit which after being submitted to NASA was refused. Hamilton Standard blamed the ILC causing the fashion company to lose their contract.

However, that wasn’t the end of the International Latex Company as a few years later NASA advertised a competition for a new suit. A handful of retired ILC employees saw their chance and broke into their old offices, stealing back their original suit designs that had previously been overlooked. After a lot of hard work the employees submitted their design to NASA who were impressed. They choose the ILC’s suit as the competition winner and deciding that Hamilton Standard would provide the oxygen tanks for the suit which we can only imagine may have been a little awkward given their previously rocky relationship.

Since their success with the original space suit, the ILC has supplied NASA with numerous items for space exploration. Along with the new next generation Z-1 suit and the Extravehicular Mobility Unit (EMU) suit used on the International Space Station, the ILC also designed the airbags that enabled Spirit and Opportunity, the two Mars rovers, to land safely on the Martian surface.

4. As you can imagine, in the microgravity of space, there are a few things you would have great difficulty with. I’m not talking about things like typing with those thick gloves or attempting to get dressed when one sock wants to head left and the other is determined to go right. Well as you can imagine everything in microgravity floats and when I say everything I mean everything…therefore going to spend a penny in space is not easy.

Nowadays astronauts staying in the International Space Station have a specially designed toilet that they can seatbelt themselves onto whilst a suction device can aid them with any waste disposal. However during the Apollo 11 mission, the solution to this all natural issue hadn’t really been solved yet and one astronaut in particular spent the entire mission on tablets that stop diarrhoea just to combat the problem. Michael Collins said himself that ‘The drinking water was laced with hydrogen bubbles’ which produced “gross flatulence…resulting in a not so subtle and pervasive aroma which reminds me of a mixture of wet dog and marsh grass.” He wrote about this in his autobiography, Carrying the Fire: An Astronaut’s Journey (1974), and I’m pretty sure it wasn’t the most pleasant memories of the crew’s trip to the moon as they were crammed together in the Command Module for three days.

5.When the Apollo 11’s Eagle Lunar Lander was separating from the CSM Colombia there was a loud pop, a bit like the noise of a champagne bottle being opened. This was because the cabin in the LM hadn’t been fully compressed before the separation. Some claim that this minor fault actually pushed the LM four miles off from where it was originally supposed to land.

6. When Neil Armstrong and Buzz Aldrin were heading out to explore the Moon they both had to remember not to fully close the door on the Landing Module behind them. The door was closed to prevent heat escaping from the cabin but not completely in case any the cabin  was somehow repressurised, which could make it difficult to get the door open. Aldrin and Armstrong joked about leaving the door open:

109:41:28 Aldrin: Okay. Now I want to back up and partially close the hatch. (Long Pause) Making sure not to lock it on my way out.

109:41:53 Armstrong: (Laughs) A particularly good thought. (Fromhttp://www.hq.nasa.gov/alsj/a11/a11.step.html )

Since then some websites have claimed there was no outside handle to get back in as the engineers back at NASA thought that the weight of a handle would affect the calculations of the descent so decided to leave the door without one! Well there was indeed a handle on the hatch complete with instructions!

image-of-a11landinggear[1]

This diagram of the LM’s landing leg indicates that it was designed to compress up to 32 inches on landing.  Apollo 11 landed more softly than expected. (Image credit: NASA)

7. We all know the famous first words of Neil Armstrong as he stepped foot onto the moon, ‘That’s one small step for man and one giant leap for mankind.’ However Armstrong’s first step out onto the Moon wasn’t small at all, in fact Armstrong had landed the Lunar Module so gently that the shock absorbers hadn’t compressed. So his first step out onto the Moon was actually close to a four foot jump onto the lunar surface.

image-of-apollo_11_flag-raising[1]

Aldrin and Armstrong raise the Stars and Stripes rather too close to the LM. (Image credit: NASA)

8. Whenever you ask children what the astronauts who visited the Moon have left behind, the first hand up in the room always mentions the American flag. However, the fate of that flag is quite sad as it was later knocked over when Armstrong and Aldrin launched the Lunar Module back into lunar orbit to join with Collins in the Command Module. After Aldrin hit the button to begin the launch he looked out the window and watched as the infamous flag was blasted away with the rest of the material left behind on the lunar surface.

9. As you can imagine, the first men to land on the Moon was a global event, everyone that could, would be watching. Due to this, NASA asked the astronauts on Apollo 11 not to engage in any religious activities that could offend, insult or isolate the rest of the world. However, Buzz Aldrin felt the opportunity was too great to let pass by. Therefore once Armstrong and Aldrin had landed safely on the Moon and were waiting to take their first steps, Aldrin radioed back to Earth asking anyone who was listening to reflect on that moment in history. Aldrin gave thanks for the opportunity and produced a small flask of wine and a piece of bread which he then consumed whilst reading from the Gospel of John. From that moment Buzz Aldrin then became the first and so far the only person to participate in the Christian ritual of Communion on the Moon. Neil Armstrong watched on in respect but never participated.

10. After gathering some Moon samples, taking some pictures and raising the American flag, Neil Armstrong and Buzz Aldrin returned to the Lunar Module, only to realise that a switch on a crucial circuit breaker had broken. This particular broken switch left them without a way to ignite the engine, so they tried to sleep while the mission control team at NASA tried to find a way to repair it. Eventually Aldrin decided that enough was enough and jammed his pen into the mechanism creating a make-shift switch. Surprisingly enough this quick-fix worked and launched both Aldrin and Armstrong off the lunar surface.

The leaden hand of bureaucracy or a joke? (Image credit: US Government)

11. As the Apollo 11 team arrived safely on the Earth, the crew were brought to Hawaii. Despite being the three most famous men at the time, as they had just landed on the Moon safely and returned, they were still asked to fill out a customs and declarations form at security. As you can imagine, in the section asking “Departure From:”the Apollo 11 crew had to write “The Moon”.

Losing the Signal - The Blackberry Story

 

There's too much work at office nowadays, I don't get any time to catch up on my reading. But every now and then, there is buzz about some new book and you just have to read it.  A few weeks back there was a general buzz in the news about Blackberry, formerly Research In Motion. It seemed that Microsoft was keen on buying the dying company. And two Globe and Mail editors were about to publish a book about the rise and fall of Blackberry. Two online newspapers had published excerpts from the book, and they covered the general theory that it was Apple's iPhone that brought down Backberry's smartphone business. The excerpts read like one of those TV documentaries were scenes were re-enacted and interviews explained them in detail.

I had to read this book. And so I did. I got myself an pirated online .epub version of the book and read it over the weekend. It was indeed a good read, and here is what I learned.

image

 

  1. The story of Blackberry is one of those untold or unheard of success stories of technology companies from the 1980s. Their story starts around the same time Microsoft and Apple started business, but never got the same kind of media spread. So they have been in business for 30 years, but they earned worldwide praise for their devices for only about 8 years, from 1999 to 2007, then they Blackberrys were the definition of a smartphone.
  2. Mike Lazaridis (born Mihal), the founder and long serving co-CEO of the company, was an engineering genius. He used to fix broken things right from childhood, and helped out fixing stuff in his school, and this set the stage for his career in the emerging telecom industry. He was the son of immigrant parents from Istanbul, his family had limited means, and he did many odd jobs in his neighbourhood and school (selling self-made quiz buzzers at one point) before he found his calling in world of electronics and communication. He built his own oscilloscope ! When he started engineering at the University of Waterloo in 1979, they had one IBM 360 computer !Discouraged with the world of big business, he decided to be his own boss by starting a consulting company that designed computer solutions for local technology companies. He and his friend Doug Fregin dropped out of University weeks before the course completion and in an unintended nod to the many lessons they had yet to learn about running a business, Lazaridis and Fregin formally registered their new company under the name Research In Motion Ltd. on March 7, 1984.
  3. At first, the company designed custom electronics for companies in Canada, and then they jumped onto the wireless communication industry designing & manufacturing pagers, the only cheapest way back then to transmit non-voice data. They worked with Ericsson to change the one-way paging system into two way, and then decided to do something about bringing e-mails to a hand held device. At the time, the only way to access e-mail was via a desktop or laptop computer. Palm was selling a wireless devices they called the Personal Digital Assistant, but it had no e-mail, only Contacts and Calendars could be shared. Mike Lazaridis himself used one, and wanted to bring these new technologies into their own range of offerings.
  4. The name Blackberry was not coined by anybody at Research in Motion. Instead, they hired Lexicon Branding, a local company renowned for its gift of selecting memorable brand names, particularly for nerdy high-tech products like Intel's Pentium and Apple's powerbook. The codename for the new device was PocketLink, and most of RIM liked and wanted that name. Somebody at Lexicon had written soothing words on a whiteboard to throw around ideas for the new name, and the words included “summer vacation,” “melons,” and “strawberry”.Next to the name of the red fruit, one of the employees had scrawled “blackberry.” It was the 40th and last name considered for the new device and Laziridis liked it instantly.
  5. The Blackberry was never intended for every user on the planet. At the time, network speeds barely allowed full HTML page browsing, and RIM wanted to sell their dedicated , encrypted e-mail services on the expensive phones to top executives who would appreciate the product. When other companies were designing multiple phone models for every demographic like age group, profession, language and country, RIM produced the same kind of phones with only a few differences between them. In 2001, they were struggling to meet sales demands for their phones, because no other manufacturer had any similar offerings. They had a plant in Waterloo in 2002 to make the phones, but they did not take the risk of opening more plants in other countries, specially third world countries. This was the main reason why their phones were priced high, and it is a mistake other companies did not make.
  6. RIM had the technology to put a full HTML web browser on a phone for years, but US and Canada network operators prevented them from doing that, fearing it would clog up their network. Steve Jobs at Apple had full control of his company, and told AT &T that they would not be involved in the design of the Apple phone at any point at all, and that they would have to support full web browsing and multimedia on the network, even the licensing deals. AT & T had no choice but to take up the offer. This is the reason why the iPhone looked cooler when it came out, it boasted of all the features other companies were denied to put on their own phones.
  7. RIM never considered Apple a threat, because while RIM was making sophisticated phones for the executives of the enterprise, Apple's phone was more like a multimedia device, and RIM predicted the new phones would clog up AT&T's network. It did. The network got so overloaded, people started complaining of dropped calls and slow internet. But what RIM did not predict was that the users didn't really care. Apple sold millions of phones in their first month alone,  more than the sales of RIM's Pearl in the last quarter. RIM took their time in responding with a touch device called the Blackberry Storm, but its touch-cum-press-down-screen proved to be a disaster, every one of the first phones had issues and had to be replaced. If RIM had designed a touch screen similar to that of the iPhone, things would have been different.
  8. There were other issues as well. A few months before the iPhone launch, RIM was hit by a patent related lawsuit from NTP Inc, a shell company, which would reap millions off RIM's profits for years. RIM was in talks with Motorola for a takeover, but those talks fizzled because Motorola did not want to sell them their patents. Motorola went down, was bought by Google, and then sold to Lenovo. RIM also had a scandal regarding back-dated options for their stock.

However towards the final chapters of the book, what plays out is that the reason the company failed in the end is the same reason they had succeeded in the first place : exclusivity. RIM did not make phones for everyone, just the elite. They sold fewer phones than rivals all through history, but those were expensive phones for the enterprise worker. Sure they were built sturdily, had great battery life, and the unique keyboard and encrypted e-mail system, but these were custom made for those who needed it. Also, a big part of RIM's revenue came from loyalty, a Blackberry user had to buy the overpriced phone all right, but then they also needed to pay RIM a monthly usage fee to use the Blackberry network for secure e-mail. And this licensing fees comprised a big part of the companies revenue. Once a Blackberry user decided to ditch the service, that loyalty was lost. And so was the monthly fee. After the i-Phone, whenever the two CEOs had to discuss on the probable next steps they could take, the decision was always between maintaining Blackberry's exclusive and signature keyboard+service system and following Apple's lead of a large multitouch smartphone or licensing BBM to other vendors, and they chose exclusivity each time. This constant pattern of choosing the lesser of two evils eventually undid whole company.

All in all, it was a good read. Some really good investigative journalism, sounded too much like a documentary screenplay. But a great insight into the another part of the technology industry from the eighties.

The Rise and Fall of Nokia - My Tryst

 

 

Today I stumbled across these videos on youtube. They are about the meteoric rise and unexpected fall of mobile devices maker Nokia. I think the downward spiral of the Finnish company is now studied by marketting students in MBA courses, because here is an example of being the first in any industry or market simply does not guarantee everlasting success. In other words, becomming number one is easy. Retaining that position is the difficult part. Once this company was the leading telecommunication handset manufacturer in the world. It still is today, in a way, counting their number of feature phones or dumb phones as some pundits call it. But they lost the battle in the smartphone market, having theoretically  invented that market. Today the only devices where their brand name can be seen is on low end feature phones which do not run a complicated smartphone OS.

I have a personal tryst with this company. I have been (and still am) a Nokia fan. Because of their design. And because at one point I did get to work for Nokia. Well, not directly. I started my career in the IT industry in 2007 with a Accenture, the American IT outsourcing company. Accenture had a long-standing partnership with Nokia, and much of their Nokia projects where being run from the Indian city of Chennai. From 2007 to 2009 I was part of the team in India which designed and developed an all-under-one-umbrella CRM system for Nokia's numerous worldwide partners. It was my first project and the best learning platform I had. In 2008 I got the fairly early opportunity to travel to Nokia's headquarters in Finland to co-ordinate in the onsite-offshore teams. I travelled twice, and got to experience the notorious Finnish winter and the effect of the nordic sun (long days in summer). I travelled there a few months after Apple had launcher the first iphone. At that time, Nokia was world leader in terms of number of units sold, and they practically owned both the feature phone and smartphone markets. Apple's venture into the smartphone market with a single, expensively priced phone on an exclusive contract with a telecom network did not pose any challenge to Nokia. Instead, they took it as a joke.

Nokia immediately went into defensive and denial mode. In the company's internal networking forums, employees where actively discussing the unique features and coolness of the new iphone, and whether this posed any danger to Nokia. The company's technology leaders responded by announcing that the iphone was Apple's doom. In internal mails (which I no longer have a copy of) the company described in detail why the iphone could not replace Nokia. Apple had only a single model, priced ridiculously high on an exclusive contract, compared to the various hundreds of Nokia models. Apple wanted to sell the same phone to CEOs of companies and world leaders, and even to college students. Should CEOs have the same phones are students ? Nokia had various models customized for every type of user, and in every price range. The first iphone did not support multitasking, while Symbian coolly supported multitasking. Apple's desire to have the user's thumb for navigation on a small screen  was impractical, since a larger screen would mean a shorter battery life. While Nokia phones boasted of battery life of couple of days even for the high end models. And then there was the service network, Nokia had the world's best customer service network for their products. The project I was on at that point was developing new software to be used on this network globally. Apple had no such end customer support, nor global partner network.

The list goes on and on, every feature of the iphone was found by Nokia to have faults. The iphone, they predicted,  would only be used by the apple's user community, which was of course a minority. Anyone reading these internal mails would  be convinced that Nokia had many decades in them before they would lose their market share. My employer at that time was promised projects for many years and we were delighted to hear that ! During my second travel to Finland in 2009, Nokia had responded by releasing the ExpressMusic phone, which had a tilt-able touch-screen and full qwerty keyboard underneath running a newer version of symbian. It still did not have multi-touch, but scored high on all other points. Even as early as 2009, Nokia had prototype version of tablet computer and what they called mini-laptops lined up for launch. We came to know of this because we were asked to include these products in the CRM system we were developing.

I left the company in 2010, and moved onto other things, happy and confident that the CRM software we had developed would bring back the lost charm to Nokia. By 2011, the writing was clear on the wall. Worldwide sales of the company dropped, and Asian handset makers overtook Nokia in the smartphone market. The recession did not help either. Nokia had to layoff a majority of their employees, many people I had worked with during my project lost their jobs. I was really really hoping they would partner with Google and embrace Android as their new smartphone OS.  I even expected them to come up with a totally new Unix based OS. Meego was too late and did not count.  While Samsung and LG where shamelessly copying the iphone design for their devices, Nokia still decided to stay true to their European modular designs. They sold their symbian project to Accenture somewhere in 2009, and transferred many of that team. But Symbian was lightyears behind what iOS and Android could do. The developer community too waned, and programmers jumped onto the new OSs and started selling their apps on appmarkets. The only relief probably was that they where no the only phone company losing. RIM, the blackberry company folded first, and turned into a joke for the industry. At least Nokia could have learnt from other's mistakes. And when Stephen Elop decided to sell Nokia to his previous company Microsoft, that was the last nail on the coffin.

I guess without innovation, a technology company cannot survive for long. Nokia's failure to act on time and address competition was probably their biggest mistake. It is a lesson technology companies will brood over forever.

But for me, they still make the best hardware for phones. I have used their phones all my lift. Those handsets never woudl heat up during conversations, and were built to last. The N72 I had bought in 2007 served me faithfully for 8 years ! It had travelled with me to 7 countries and had weathered rain , sand and snow. I have used the sim cards of 5 work networks on it. The 3310 was my first cell phone. I was an expert on composing ring tone on that hone using the composer. I developerd the J2ME version of Sokoban for symbian during my college years to study the platform.My entire family use Nokia phones, even today.

So long, Nokia.

NOKIA - 150 years

 

NOKIA was founded on this date 150 years ago.

Sadly, even it's wikipedia page did not get any visitors for the occasion.

Well, they remembered it at their own offices:

From paper to phones to acquisition by Microsoft and its recent revival, the story of Nokia goes back 150 years to May 12, 1865 when Knut Fredrik Idestam secured the permit to set up his paper mill in southern Finland. Idestam's second mill was on the banks of the Nokianvirta river. Nokia derives its name from the river. After diversifying into rubber, cables and electronics Nokia entered the world, that it would later conquer, of mobile communications in 1968.

main-1-nokia-microsoft-2604

 

In 1979 Nokia and Salora got together to establish Mobira Oy, a radio telephone company. 1981 marked a new era for Nokia when the Nordic Mobile Telephone service was set up. It was the world's first international cellular network and Nokia launched its first car phone, Mobira Senator, in 1982.

nokia-150-years-120515

150 years ago, on May 12, 1865, Nokia founder Knut Fredrik Idestam secured the permit to set up his paper mill in southern Finland.

2-nokia-microsoft-260414

The Mobira Talkman, a giant 'wireless' car phone was introduced in 1984. Much of the weight was attributed to its battery.

3-nokia-microsoft-260414

In 1987, Nokia phones shed some weight with the launch of its first handheld mobile phone - the Mobira Cityman. The Mobira Cityman 900 weighed 800 grams and cost about 4,560 euros (approximately Rs 267,200). The phone got the nickname "Gorba", as the then Soviet leader Mikhail Gorbachev was famously pictured making a call from the phone.

4-nokia-microsoft-260414

When the GSM network was rolled out in 1991, Nokia released its first digital handheld GSM phone, the Nokia 1011. The world's first first GSM call was also made using a Nokia device.

5-nokia-microsoft-260414

Nokia followed up on the 1011 with the Nokia 101 phone in 1992. The phone came with an extendible aerial.

6-nokia-microsoft-260414

Launched by Nokia in 1994, the Nokia 2110 was the first phone to feature the Nokia Tune as a ringtone. The Nokia Tune is derived from Gran Vals, a classical guitar piece, composed by Francisco Tarrega in the 19th century. The Nokia 2100 series went to to be a big success. Nokia had expected to sell about 400,000 units, but 20 million phones were sold the world over.

7-nokia-microsoft-260414

The banana-shaped Nokia 8110 was launched in 1996. This slider-phone found a place in popular culture when it was featured in the 1999 blockbuster The Matrix.

8-nokia-microsoft-260414

The 1997 Nokia 6110 was the first device to feature the addictive Snake game. The game is available on about 350 million mobile phones. The hot-selling 6110 also boasted of some other Nokia firsts: infra-red port and menu icons.

9-nokia-microsoft-260414

Launched in 1998, the Nokia 8810 was the first mobile phone without an external antenna. The slider form of the phone also added to its appeal. By 1998 Nokia was the world leader in mobile phones, a position it holds till date.

10-nokia-microsoft-260414

2002 was an year of innovation at Nokia. The Nokia 6650 launched was Nokia's first 3G phone launched that year.

11-nokia-microsoft-260414

Also released in 2002, the Nokia 7650 was the first Nokia phone with a built-in camera. The 7650 was also one of the first Nokia phones to have a colour display.

12-nokia-microsoft-260414

Another 2002 innovation at Nokia was the 3650. The Nokia 3650 was the first phone by Nokia to be able to record video.

13-nokia-microsoft-260414

Nokia launched its mobile-phone-cum-handheld-gaming-device N-Gage in 2003. In 2009 Nokia announced that it will stop development of N-Gage games and would discontinue the N-Gage service by the end of 2010.

14-nokia-microsoft-260414

Nokia launched its Nseries phones in 2005. These entertainment-cum-communication devices form Nokia's top line of offerings. The N70, N90 and N91 were the first of the series to be introduced.

15-nokia-microsoft-260414

In April 2010, Nokia announced the N8, it's new flagship phone. The phone was launched in October 2010.

16-nokia-microsoft-260414

Faced with dwindling sales and stiff competition from Android and iPhone, Nokia ditched its ageing Symbian platform in favour of Microsoft Windows Phone software. Nokia hoped that this move would help it reclaim the smartphone crown and bring back its mojo. The company announced its first Windows Phone devices, Lumia 800 and Lumia 710 at the Nokia World 2011 in London on October 26.

17-nokia-microsoft-260414

To further strengthen its hold on the feature phone segment and get an entry into the entry-level smartphone market Nokia introduced its Asha range of phones in 2011.

18-nokia-microsoft-260414

At the Mobile World Congress 2012, Nokia unveiled its Nokia 808 PureView smartphone with a 41 megapixel camera usinng a new camera technology. Though the phone was not a success, it laid the framework for cameras in future Nokia devices.

19-nokia-microsoft-260414

In July 2013, Nokia introduced a new smartphone, the Lumia 1020, with a powerful 41-megapixel camera (last seen in the PureView 808) in a bid to catch up with rivals Samsung and Apple.

20-nokia-microsoft-260414

On September 3, 2013 Microsoft and Nokia announced that Microsoft is buying Nokia's devices and services business, and getting access to the company's patents, for a total of 5.44 billion euros ($7.2 billion) in an effort to expand its share of the smartphone market. Microsoft will pay 3.79 billion euros ($5 billion) for the Nokia unit that makes mobile phones, including its line of Lumia smartphones that run Windows Phone software.

21-nokia-microsoft-260414

Foraying into the phablet market, Nokia announced the launch of its first 6-inch smartphones - the Lumia 1320 and Lumia 1520.

22-nokia-microsoft-260414

Nokia introduced its fist tablet - Lumia 2520 - in 2013.

23-nokia-microsoft-260414

Nokia announced its first-ever Android-based smartphones early this year. The first three phones in the family - the Nokia X, X and XL - run on the new Nokia X software platform, that is based on Google's Android. These phones were later discontinued.

24-nokia-microsoft-260414

Nokia, on April 25, completed the 5.44 billion-euro ($7.5 billion) sale of its troubled cellphone and services division to Microsoft, ending a chapter in the former world leading cellphone maker's history that began with paper making in 1865.

25-nokia-microsoft-260414

In November 2014, Microsoft released the Lumia 535, the first Lumia phone without Nokia branding.

microsoft-lumia-535-111114

In the same month as the Lumia 535 launch, Nokia announced its plans to bring its brand back to consumers with a new tablet - the Android-based Nokia N1.
