Struggling cable network OWN saw the kind of triple-digit ratings increases over predecessor Discovery Health that it had been seeking with last night’s launches of The Rosie Show and Oprah’s Lifeclass. OWN had been stuck at the ratings levels of Discovery Health season to date and dipping below them in the most-recent third quarter. The network put all of its eggs in the Rosie/Lifeclass basket, effectively doing a relaunch of the network with the show’s premieres, which were simulcast across five Discovery cable networks. On OWN, The Rosie Show, hosted by Rosie O’Donnell, averaged a respectable 497,000 viewers, up 238% from Discovery Health’s October 2010 average in the 7 PM slot. In women 25-54, Rosie Show posted a .44 rating, up 267%.
