"With passage of this legislation, I am confident that broadcasters will think twice about pushing the envelope," said Representative Fred Upton, a Michigan Republican, who is chairman of the House telecommunications panel and author of the bill. "Our kids will be better off for it."
The White House said in a statement that it strongly supports the legislation that "will make broadcast television and radio more suitable for family viewing."
A similar bill has been introduced in the Senate, where it has broad bipartisan support. Senator Ted Stevens, an Alaska Republican who is chairman of the Commerce Committee, has said he wants to act on the bill quickly, but he has not given a timetable.
Any differences in the two bills would have to be resolved before it can go to President Bush for his signature. Last year the two chambers were unable to reach a compromise.
Opponents said they were concerned that stiffer fines by the Federal Communications Commission would lead to more self-censorship by broadcasters and entertainers unclear about the definition of "indecent."
They cited the example of several ABC affiliates that did not air the World War II drama "Saving Private Ryan" last year because of worries that violence and profanity would lead to fines, even though the movie already had aired on network television.
Representative Jerrold Nadler, Democrat of New York, said changing the channel is the best way for families to avoid racy programming.
"But the prurient Puritans of this House are not satisfied with free choice and the free market," Nadler said. "Instead, they want the government to decide what is or is not appropriate for the public to watch or listen to."
Andrew Jay Schwartzman, chief executive officer of the Media Access Project, a law firm that represents small broadcasters, said some of his clients already are censoring themselves because they cannot afford to risk fines at the current level.
