The Apple iPad is the most popular tablet computer, one that helped build the market for the devices. Introduced in 2010, the iPad was first met with skepticism from critics who wondered if there would be a market for a large handheld device with no keyboard, but it quickly proved to be a popular and fast-selling item.

There have now been six versions of the iPad, with a number of innovations along the way including Retina Display. Apple has sold more than 250 million iPads through just the first five years of operation, and the release of new versions has become a highly anticipated event.
