At least, that's the conclusion research firm IHS came to upon seeing growth in Apple's online video sales. Apparently Apple, up against competition from Walmart (Vudu) and Amazon, saw its market share go up from 64.9% in the first half of 2010 to 65.8% in the first half of 2011. Not exactly stock-enlarging numbers, I realize. There's also the fact that this report leaves Netflix completely out of the equation. But IHS found that "iTunes experienced the largest revenue increase growth among all online movie providers during the first half" which is very good news for stockholders.
