What's the hubbub with The Hub, Bub? It's the new kids TV network that will occupy the airwaves previously devoted to the Discovery Kids network.

The Hub, a joint project by Discovery Communications and toy and game company Hasbro, launches on Oct. 10 (yes, 10/10/10 at 6AM ET) in 60 million homes, and is best described as Nickelodeon-meets-TV Land.

Bindi Irwin, the daughter of the late Steve Irwin, will carry on her father's legacy. The 8-year-old sweetheart is currently filming a documentary series for Discovery Kids. The wildlife series is called Bindi, The Jungle Girl. People.com has a quote from her that will tug at your heartstrings, she says, "I'm trying to get across the message that don't be afraid of animals, they're just put here on this earth to help the environment and everything like that." Steve Irwin will actually appear in some of the 27-part series, which he was filming when he died, but Bindi is the star. In fact, his death will never be mentioned during the series. Just like her dad, Bindi plays a girl who is fearless when it comes to nature. Bindi, The Jungle Girl will begin airing on Discovery Kids in January 2007

NBC has to look for new Saturday morning programming. For the last four years, Discovery Kids has paid NBC to air programming from 10 am to 1 pm on Saturdays. The deal was an effort to expand the Discovery Kids brand, which it did by more than 100 percent, growing from 21 million to 43 million households since 2002. Discovery didn't give any reason for splitting from NBC, but NBC said the split was amicable and in the best interest of both networks.

More changes are underway on Saturday mornings. CBS is developing a three-hour kids' entertainment block called CBS Secret Saturday Morning Slumber Party, which debuts this fall.
