After 2 1/2 years of negotiations, Family Guy creator Seth MacFarlane has inked a new mega overall deal with 20th Century Fox TV that would make him the highest-paid TV writer-producer, according to The Hollywood Reporter.

The pact, which could be worth more than $100 million, will keep MacFarlane at 20th TV through 2012. It covers his services on Family Guy and his other two animated series for 20th TV and Fox -- American Dad! and the upcoming Family Guy spinoff "The Cleveland Show" -- as well as his TV development, including a multicamera comedy with Family Guy writer Gary Janetti. It also encompasses new-media projects related to MacFarlane's TV series as well as DVD and merchandising revenue from them. ("Guy" alone has grown into a $1 billion franchise with red-hot DVD and merchandise sales.) Additionally, the deal is said to include advances towards MacFarlane's back end, which is expected to increase under the new deal.

"I get a lot of pleasure out of making shows," MacFarlane said. "It's a bonus to be getting paid well for it, and it's a double bonus to be getting paid exorbitantly for it."

Neither side would comment on the size of the deal, with 20th TV chairman Dana Walden noting only that "no one will ever have to offer Seth a handout of any kind."

MacFarlane's deal is expected to eclipse the $60 million five-year feature/TV pact J.J. Abrams inked with Paramount Pictures and Warner Bros. TV in 2006.
