On January 9, 2007, Apple Inc. CEO Steve Jobs (above) unveiled
the iPhone—a touchscreen mobile phone with an iPod, camera
and Web-browsing capabilities, among other features—at the
Macworld convention in San Francisco. Jobs, dressed in his
customary jeans and black mock turtleneck, called the iPhone
a “revolutionary and magical product that is literally five years
ahead of any other mobile phone.” When it went on sale in the
United States six months later, on June 29, amidst huge hype,
thousands of customers lined up at Apple stores across the
country to be among the first to purchase an iPhone (below).
