Tonight is a big night for Oprah’s OWN network. The ratings challenged cable channel premieres Oprah’s Lifeclass and Rosie O’Donnell returns to talk TV with The Rosie Show. Airing across all five Discovery network channels, a lot is riding on the two former daytime titans’ shoulders. My favorite The Rosie Show promo is of Oprah and Rosie trying to meditate.
