Apple (NASDAQ:AAPL) dominates the market for Internet video sales. According to NPD, iTunes' shares of electronic sell-through for TV shows climbed to 67% in 2012.

That's an astounding number when you consider that Amazon.com (NASDAQ:MSFT), Google (NASDAQ:GOOGL), and Microsoft (NASDAQ:MSFT) all offer TV seasons and episodes for sale. Viewers seem to prefer Apple, iTunes, and the device ecosystem so many of us have come to rely on for watching our favorite programming, says Tim Beyers of Motley Fool Rule Breakers and Motley Fool Supernova in the following video.

Why should investors care? While missing pieces remain, Apple looks best positioned to create an infrastructure that could entirely circumvent cable companies to the benefit of users and Apple shareholders. The only question is whether the Mac maker has the guts to grab the opportunity.
