This Week in Tech History: iPhone is Introduced

A new way to listen to music is unveiled, a tech mogul steps down and a device that changed the way we communicate was introduced… It all happened This Week in Tech History.

This week in 1949 – The Radio Corporation of America, sometimes known as RCA, announced a new 7-inch, 45-rpm phonograph record. Soon, the 45, the record with the big hole in the middle, would change the pop music business.

And this week in 2007 – Apple chairman Steve Jobs introduced the iPhone at the Macworld Expo in San Francisco. The 4GB version of what became the 2007 invention of the year went on sale in June for $499.
