CHICAGO (thefutoncritic.com) -- ABC and CBS both made a few changes to their respective fall start dates this week: the Alphabet wants to work around the California recall while the Eye wants to take advantage of the success of "Big Brother 4."

ABC has announced it will move the premieres of all four of its Tuesday comedies to Tuesday, September 23. The network had previously scheduled hourlong premieres of "Eight Simple Rules..." and "According to Jim" on that date, with newcomer "I'm With Her" and sophomore "Less Than Perfect" bowing a week later. The shift was done to give "Her" and "Perfect" two weeks instead of one before being pre-empted by the network's expected California recall coverage on October 7. It's not clear if any of the other major networks will disrupt their usual lineups to cover the recall.

As for CBS, the Eye has ordered two additional episodes of its latest version of "Big Brother." The two new installments will push the fourth season finale to Wednesday, September 24, instead of the previously planned Septmeber 17 wrap-up. The move bumps the premieres of the newly relocated comedies "King of Queens" and "Becker" to October 1 and October 8 respectively. CBS hopes the "Big Brother" finale will provide an extra boost to the bow of "The Brotherhood of Poland, N.H." that same night. In addition, the extra week allows CBS more time to promote "Queens" and "Becker's" move to Wednesdays which many view as the network's riskiest move this season.
