Congress gave notice to broadcasters Wednesday that they will pay dearly for crossing the line with offensive material like Janet Jackson’s 2004 Super Bowl “wardrobe malfunction,” passing legislation that would multiply indecency fines 10 times.

The 379-35 House vote on the Broadcast Decency Enforcement Act sends the bill to President Bush for his signature. The bill, which already passed the Senate, increases the top indecency fine the Federal Communications Commission can levy from $32,500 to $325,000 per incident. Bush is expected to sign it.

“Those who abuse the public airwaves by airing sexually graphic material will now be subject to greater fines, a much better deterrent than the current paltry fines,” the Parents Television Council, an aggressive critic of indecency on the public airwaves, said after passage of the Senate bill.
