There is no doubt that Apple's iPhone single-handedly changed the cellphone market. It practically re-created the concept of a smartphone and there is no doubt either that this phone is the ultimate king of the mobile market, despite the Android having a larger share if you put all those hundreds of devices together.
In the week that the iPhone completes 5 years of existence (since the unveil of the first model in 2007), American research firm Strategy Analytics has released some data revealing that the iPhone family has brought Apple over $150 billion in revenue throughout the years, selling 250 million units.
The figures above include all the iPhones, since the first one up until the most recent one, the iPhone 4S. Among them, the most popular in terms of revenue and units sold is the iPhone 4. While the popularity of the the phone isn't anything new, Strategy Analytics predicts tougher next five years.
Why? Other companies are putting bigger and better efforts in building their smartphones, for instance, Samsung's Galaxy S line is getting a lot of attention in the consumer market and the South Korean company is giving its best to put their smartphones in the spotlight.
There is also the pricing of the iPhone. While other phones couldn't compete with the iPhone in quality, it was ok to overprice it, but now, there are phones considered even better than the iPhone which are being sold for much less than.
And overall, the growth of the smartphone market is slowing down. Strategy Analytics expects the whole market to observe a smaller expansion this year, specially due to the fact that most mobile customers in the U.S. and Europe have already migrated to smartphones.
