Nielsen will expand the definition of TV viewing it measures, rolling out "a comprehensive plan to capture all video viewing including broadband and Xbox and iPads," according to unnamed sources cited by Alex Ben Block. By September Nielsen will implement tools measuring viewership on streaming and over-the-top services, on TV-enabled game systems and, in a limited way, tablet devices. A second phase, with "the overall goal to attempt to capture video viewing of any kind from any source," will roll out more slowly.
