NBC vet will be the net's new entertainment president with Liguori becoming entertainment chairman

Recently dismissed NBC bigwig Kevin Reilly's move to FOX is now official.

Reilly, who helped develop and nurture shows ranging from "The Shield" to "The Office" to "Friday Night Lights" in his tenures at FX and NBC, will become FOX's new entertainment president.

As part of the network's restructuring, Peter Liguori will shift from entertainment president to entertainment chairman.

"The television industry has changed more in the last five years than in the past 20," says News Corp President and COO Peter Chernin. "We need to be structured in a way that puts us in the best position take advantage of the myriad new opportunities digital technology has afforded the broadcast television business. When Peter Liguori approached me with the idea of re-teaming with Kevin Reilly, I thought it was a bold move to redefine the structure of the network behind a pair of dynamic executives who have a proven track record of advancing the medium."

From 2000 through 2003, Liguori served as FX's president and CEO, while Reilly worked under him as president of entertainment. During that time they helped the cable network, a corporate sibling to FOX, focus its creative energies and brand around new programs like "The Shield" and "Nip/Tuck."

Under the new FOX structure, Reilly will report to Liguori, whose new duties will shift away from programming and toward "developing new models for FOX broadcast content to best leverage the brands across all emerging platforms," according to the network's press release.

"I'm thrilled to be working with my good friend Kevin again. We have complementary strengths, but more importantly, we have fun working together and we enjoy sharing that spirit with the rest of the team," says Liguori. "FOX is television's premier brand and I am excited to take on a role that requires more long-term strategic vision at a time when FOX has the opportunity to become an even bigger force in this quickly evolving media landscape."

Although he developed hits including "Heroes," "My Name Is Earl" and "Deal or No Deal" during his time at NBC, Reilly wasn't able to pull that network out of fourth place among adults 18-49, a key demographic ruled by FOX in recent years. Reilly was relieved of his duties over the Memorial Day weekend, but he didn't wait long to find a new gig.

"I couldn't be happier to rejoin Peter Chernin and the Fox family and to collaborate again with my good friend Peter Liguori, who shares my view of being competitive by being creatively adventurous," Reilly says. "The company has a top-down vision and the network has a collaborative environment and winning track record fostered by Peter Liguori, which I personally look forward to as a refreshing change of pace, and have no doubt will be the formula to keep FOX the leader on all fronts for years to come."
