Oprah Winfrey Oprah Winfrey

With less than a month to go before the launch of her new cable network OWN, Oprah Winfrey is calling on the big guns to help spread the word. And by big guns, we mean music from Will.I.Am and lots and lots of balloons.

In an ad premiering in movie theaters across the country Friday, Winfrey steps in front of the camera to promote her latest venture. "What if I could take every hero who inspired me, every lesson that motivated me, every opportunity that was ever given to me, and give it to you?" she asks in the clip. "And now here we are. This is our day. This is our moment. It all begins here: OWN."

What will air on Oprah's OWN network?

OWN launches on Jan 1, 2011. 3-D flat screen TV and all-expenses paid Caribbean cruise not included.
