As part of its annual Watchathon week (going on right now), Comcast compiled detailed information about how viewers nationally, and in its biggest markets, consumed programming via Xfinity [on Demand platform] between April 1, 2015, and the end of last month. While the company doesnt reveal specific numbers for shows, it does rank them in order of popularity. But, unlike Nielsen, it also doesnt distinguish between shows currently in production and those which signed off years ago: If its available to stream, its eligible to make the top ten. And this quirk greatly benefits HBO, whose on-demand platform allows subscribers to dive deep into the networks library of original offerings, going all the way back to 1990s offerings such as Oz. Per the data Comcast made available exclusively to Vulture, three HBO catalogue titles The Sopranos, The Wire, and, God help us all, Entourage continue to be massively popular on VOD. In fact, Entourage was the fourth-most-watched show on Xfinity during the past year nationally, just below Empire and ahead of AMCs The Walking Dead. If that seems beyond belief, remember: The Entourage movie, backed by millions of marketing dollars, was released last June.
