Seth MacFarlane has signed an overall deal with 20th Century Fox TV which would reportedly make him the highest-paid writer-producer working on television.

According to The Hollywood Reporter, the new deal could be worth more than $100 million and it keeps MacFarlane at 20th Century Fox TV through 2012.

Among the properties covered by the pact are MacFarlane's current FOX shows "Family Guy" and "American Dad!," plus the "Family Guy" spin-off "The Cleveland Show," which is expected to be picked up to series for next season. It covers his roles as writer-producer on the three shows and also encompasses his capacity as lead vocal talent.

In addition to the three animated series, MacFarlane is also developing a live-action, multi-camera sitcom with "Family Guy" scribe Gary Janetti.

MacFarlane's previous deal with 20th Century Fox TV actually expired over a year ago and although negotiations have been active and ongoing, things haven't always been smooth between the wunderkind and his studio.

During the writers strike, MacFarlane expressed very public disapproval with the studio's decision to complete several episodes without his involvement. In addition, MacFarlane is part of a recent suit filed by 16 "Family Guy" writers against the studio stemming from the 2005 DVD "Family Guy Presents Stewie Griffin: The Untold Story."

In order for MacFarlane's deal to reach the $100-plus million figure speculated in the trades, "Family Guy" would likely have to run for the duration of the pact and the other shows would likely have to move into a successful level of syndication.

J.J. Abrams' $60 million/5-year deal with Paramount Pictures and Warner Bros. TV, inked in 2006, was considered to be the previous industry peak.
