History of Apple Inc.
The first version of the iPhone became publicly available on June 29, 2007 in selected countries/markets. It was another 12 months before the iPhone 3G became available on July 11, 2008. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. This 12-month iteration cycle has continued with the iPhone 4 model arriving in similar fashion in 2010, a Verizon model was released in February 2011, and a Sprint model in October 2011, shortly after Jobs' death.

The first laptop was produced in 1981 but it took more than a decade of development for the designs to approach current (2016) levels of portability and capacity, and hence uptake. Apple produced the first smartphone (the iPhone) in 2007 and the first tablet (the iPad) in 2010. In 2015 there were 4.43 billion mobile phone (cellphone) users in the world, of which 2.6 billion had smartphones. In the US, 45% owned a tablet computer in 2014 and 92% owned a mobile phone; for younger adults aged 18–29, only 2% didn’t own a mobile phone and 50% had tablets.
