Discovery Communications Inc. is increasing its stake in Burbank cable channel Hub Network, which will be renamed to reflect broader family programming. Hub Network was founded in 2010 as a 50-50 joint venture between Discovery, in Silver Spring, Md., and Pawtucket, R.I. toy maker Hasbro Inc. Discovery is raising its stake to 60 percent while Hasbro will reduce its to 40 percent. Beginning Oct. 13, Hub Network will become Discovery Family Channel and will air children’s programming such as “My Little Pony” and “Transformers Rescue Bots” during the day and family shows in the natural history, animals and science genres in evening prime-time hours. While the network reaches 70 million households, consistent ratings success has proved to be elusive in the crowded children’s and family programming market. Competitors include Disney Channel and Disney XD, owned by Walt Disney Co.; Nickelodeon, a division of Viacom Inc.; and Cartoon Network, owned by a division of Time Warner Inc. “The next chapter of our collaboration will harness the content strengths of both Discovery and Hasbro to program Discovery Family Channel with highly-rated award-winning storytelling around Hasbro’s brands and Discovery’s non-fiction shows that appeal to both children and families alike,” said Hasbro Chief Executive Brian Goldner in a prepared statement. Concurrent with the other changes at Hub, Tom Cosgrove was named general manager with management responsibilities over network operations and programming. Margaret Loesch, who was the channel’s first chief executive, announced in June that she would leave the network when her contract expires at the end of the year.
