Pro-choice groups are making too much of an anti-abortion commercial that CBS plans to broadcast during the Super Bowl featuring University of Florida quarterback Tim Tebow and his mother. It's just a commercial, after all. Still, it's worth noting that CBS' decision reflects a policy change. In the past, CBS has prohibited advocacy ads. For example, CBS refused to broadcast a commercial during the 2004 Super Bowl by the United Church of Christ about how "Jesus didn't turn people away," including gays. CBS said this week that, under its new policy, the UCC ad would air.
