Apple dominates the home digital-video sector, in much the same way it dominates digital music. iTunes’ share of electronic sell-through (EST) for television shows reached 67 percent in 2012. EST television sales from Xbox Video, Apple’s nearest competitor, comprised 14 percent of the market. When it comes to feature-length movies, iTunes boasted a 65 percent share of EST, with Amazon and Xbox Video far behind at 10 percent each.

It’s not even close.
