The House passed legislation Thursday that would fine broadcasters up to $500,000 per violation for airing indecent programming from 6 a.m.-10 p.m.
The legislation -- a response to Janet Jackson's Super Bowl breast exposure, seen by millions of families with children -- passed 391-21.
The bill would authorize the Federal Communications Commission, which currently can't fine violators more than $27,500, to fine TV networks and on-air performers for willful violations.
The FCC would have 180 days to resolve indecency cases. A broadcast licensee with three violations in an eight-year period could have its license revoked.
Cable operators and networks are not covered by the legislation or by current FCC indecency regulations.
