When you consider the increasingly stiff competition of the streaming device industry, Apple's ability to capture better than half of this market with the Apple TV is an impressive feat.

According to a report Tuesday from Frost & Sullivan, the Apple TV now accounts for 56% of the global IP streaming devices market. Apple's nearest competitor - Roku - actually isn't near Apple at all with just 21% of the market.

TiVO - yes, TiVo is still around - placed a distant third with 6.5% of worldwide sales. The remaining 15.9% was divided among Sony, Boxee TV, Logitech Revue, Vizio, and other miniscule players in the game.

So what has helped Apple secure such a dominant share of this market? iPhones and iPads haven't hurt, says analyst Dan Rayburn.

“Apple TV’s AirPlay feature was strategically crafted to simplify the process of transferring laptop and tablet displays to a TV screen, and it is AirPlaying – not (online video) streaming – that is the primary reason for purchase of Apple TV devices,” Rayburn says.
