The iPad is Apple’s flagship entry into the tablet market, but not its first. Company founder Steve Jobs introduced the first version of the product in 2010, and it became an instant success. Prior to that, Apple had tried tablets in the 1990s, with the Newton MessagePad 100. Utilizing the iOS mobile operating system from the iPhone series of products, Apple grew the screen size to 9.7 inches for the first iPad. It was seen as a mix of iPhone, eReader, and laptop. Subsequent releases have included an iPad mini (7.9-inch screen) and the lighter, higher-powered iPad Air. There have been six versions of the iPad in all.
