Silicon Alley Insider's Michael Learmonth is now saying ABC looks like it's the top TV network on the Web, based on unique viewers to its video in February. But in average time spent per viewer, CBS knocks it out of the park. According to SAI, quoting Nielsen Online's VideoCensus it's:
ABC: 4.6m uniques / 48.6 minutes
CBS: 2.9m uniques / 69.1 minutes
If I were a CBS exec, I'd be trumpeting the time spent figure. That, they can argue, is true "engagement." Once folks are on, they stay on (and not only view a lot but also can be served a lot of ads).
