Netflix and Hulu occupy almost entirely separate camps of digital streaming, Nielsen learned in a study Wednesday. Both are now available on many platforms, but Netflix is the dominant form by a wide margin on non-PC devices, including iPads, game consoles, and Internet-aware media hubs, ranging from a three-to-one ratio on Apple's tablet to seven or eight times higher. Hulu only wins out on computers but often does so by a wide margin, with 89 percent of its viewers watching on a computer versus just 42 percent of Netflix owners wanting to do the same.
