Oprah Winfrey continued her ascent from entertainer to entertainment mogul with the announcement yesterday that she is joining forces with Discovery Communications to launch a self-branded cable network.
The Oprah Winfrey Network will debut in the second-half of 2009 in more than 70m US homes, expanding a media platform that the talk show host has used to endorse everything from books and charities to Senator Barack Obama's presidential campaign.
