Since the release of the iPhone 4S, Apple (AAPL) has touted its intelligent voice assistant Siri as a key feature of the iOS ecosystem. The startup company behind the app originally launched Siri as standalone program on the App Store and had plans to release Android and BlackBerry versions in the future. Siri was quickly acquired by Apple, however, and plans to expand the app were cancelled.

According to a report from The Huffington Post, Verizon (VZ) had actually signed a deal with the creators of Siri to feature the voice assistant on its DROID line of smartphones several months before the company was approached by Apple. The wireless carrier even created commercials touting the unique feature, although they never saw the light of day.

After two months of availability on the App Store, Apple acquired Siri in 2010 and the rest is history.
