What format is iBooks?
The supported e-book formats by iBooks are EPUB and PDF. As of version 2.0, iBooks also supports a proprietary iBook format (IBA), generated with the iBooks Author tool. This format is based upon the EPUB format but depends upon custom widget code in the iBooks app to function.
When did the first iBook come out?
iBook. Announced in July 1999 at Macworld New York, the iBook was perhaps the most anxiously awaited Apple computer ever. Aimed at the same consumer market as it's big brother, the iMac, the iBook filled the 2×2 consumer/pro/desktop/portable matrix that Steve Jobs had first detailed more than a year earlier.
