Hoping to load their Friday schedules with new shows for the remainder of the season, ABC and CBS have ordered additional episodes of the comedy “8 Simple Rules” and the freshman drama “Numb3rs.”

Currently airing in a double-dose on Fridays at 8 p.m. EST, “8 Simple Rules” has been extended for two additional episodes. The season order for the Touchstone TV series, which stars Katey Sagal and David Spade, is now up to 24 episodes.

Through its first 16 airings, “8 Simple Rules” is averaging 7.03 million viewers this season. However, the show’s recent run of 8:30 repeats have actually averaged nearly 7.9 million and have seemingly strengthened the overall numbers for the franchise.

Over on CBS, “Numb3rs” has been extended by four episodes. The Paramount Network TV drama, which stars Rob Morrow and David Krumholtz, would now be up to 12 episodes for the season.

“Numb3rs” had a fantastic premiere, airing after CBS’ coverage of the AFC Championship game and drawing 24.9 million viewers. Since the show moved to its regular Friday, 10 p.m. EST time period, though, its ratings have fallen three consecutive weeks. Through its first two airing, though, “Numb3rs” has still averaged more than 13 million viewers per week, regularly winning its hour.
