Fox has renewed 24, The O.C., Malcolm in the Middle and The Bernie Mac Show for next season. The network also picked up Mad TV for three additional seasons. (That '70s Show, King of the Hill and The Simpsons were renewed earlier this year. Arrested Development remains on the bubble.) Speaking of 24, Tuesday's thrilling hour featuring a knockout performance by Elisha Cuthbert attracted 11 million viewers, matching the show's best ratings of the season. Translation: 24 is back, folks.
