Nokia (Microsoft) Cellphone Evolution

Nokia Cellphone Timeline - RF CafeNokia has been in the news lately for having sold its cellphone line to Microsoft for $7.2 billion (US). Was it a good move? At least immediately, it depends on whether you owned Microsoft stock or Nokia stock. Responding to the news, Microsoft's stock shed $1.52 (-4.6%) to close Tuesday at $31.88. Nokia's shares surged $1.22 (+31%), to finish at $5.12.  Microsoft's Windows Phone operating system has been in Nokia phones since 2011. Nokia was knocked from its #1 rank pedestal a couple years ago and is currently in the #2 slot, with Apple following, then China's ZTE.

Nokia Mobira Senator - RF CafeNokia's debut in the cellphone realm was in 1992 with the Mobira Senator. It wasn't quite a bag phone, but it was about as large and heavy. The rather large chart below illustrates every cellphone model released by Nokia between 1992 and 2007 (16 years). It covers 1G through 3G models (4G was just a concept at the time). With the rate at which new products are released these days, a similar chart covering 2008 through 2012 (5 years) would probably have as many or more phone models. Here is a short written history of Nokia.

While searching for Nokia info I ran across a website with some of the old magazine advertisements. This Chuck Norris ad was amongst them. If you're a Chuck fan, then you'll probably also appreciate this list of Chuck Norris jokes. Examples re phones: ‡ When Alexander Graham Bell invented the telephone he had 3 missed calls from Chuck Norris. ‡‡‡ Chuck Norris doesn't call the wrong number. You answer the wrong phone. ‡‡‡ The phrase 'dead ringer' refers to someone who sits behind Chuck Norris in a movie theater and forgets to turn their cell phone off. ‡‡‡ Chuck Norris can strangle you with a cordless phone.

BTW, if you like looking at these types of charts, click on this Google image search.
