With a suite of channels that includes Discovery Channel, TLC, Animal Planet and OWN: The Oprah Winfrey Network, there was plenty of ground to cover.

Luckily, they had Oprah there to sell it.

Yes, talk show queen turned media mogul Oprah Winfrey herself was in attendance at Jazz at Lincoln Center, and revealed the 2011/2012 OWN programming slate on stage.

She was joined by Rosie O’Donnell, who will be making her return to daytime with a talk show on OWN later this year. O’Donnell performed a song and dance routine with a troupe of male dancers.

Discovery had other big names in attendance, inducing actor Morgan Freeman, who hosts and produces the program “Through the Wormhole” on Science, and magicians Penn & Teller, who have a new show “Penn & teller’s Secrets of the Universe” on Discovery later this year. Billy Ray Cyrus also unveiled his new show for TLC, “Homecoming,” which reunites military men and women with their families, while SNL’s Andy Samberg told some jokes in advance of his gig as “Chief Shark Officer” during 2011′s Shark Week.
