The most famous initials since "OJ" return to TV screens when the second season of "The O.C." premieres on Fox in its new time slot at 8 p.m.

Fox's breakthrough hit from last season is clearly the network's new heavyweight contender.

It's looking to slip, midseason, into the most heated time slot on the most heated night of the week - sizing itself up against NBC's "Joey" and CBS's "Survivor."

Both of those series, however, have been disappointing so far, which might provide "The O.C." with the perfect opportunity to prove it's legit.

"The O.C." is the highlight of the Fox lineup that's firing up over the next several days. Emmy-award-winning sitcom "Arrested Development" headlines a Sunday lineup, premiering at 9:30 p.m. Other shows making their season debuts are "King of the Hill," "Malcolm in the Middle," "The Simpsons" and "My Big Fat Obnoxious Boss" from 7 to 10 p.m.

And new shows like "The Rebel Billionaire: Branson's Quest for the Best," starting with a two-hour premiere at 8 p.m. Tuesday, and "House," starting at 9 p.m. Nov. 16, will seek to carry Tuesday night for Fox.
