NEW YORK (AP) — Federal regulators have weakened rules meant to support independent local media.

Now, one company can own newspapers and broadcast stations in one market, undoing a ban in place since 1975. Thursday's decision by the Federal Communications Commission also makes it easier for one company to own two broadcast TV stations in one market and coordinate operations with stations owned by others.

Although the changes won't affect AT&T's pending bid for Time Warner and its cable channels, they come as cable and phone companies have grown into industry giants through acquisitions. The newspaper and broadcasting industries say they need the changes to deal with growing competition from the web and cable companies.

The Republican-dominated FCC approved the changes in a 3-2 vote along party lines. The two Democratic commissioners and other critics say that dumping these rules, by encouraging consolidation, hurts media diversity. Free Press, a group that opposes media mergers, said Thursday that it will challenge the rule changes in court.

"This act will pave the way for massive broadcast conglomerates to increasingly provide local viewers with nationalized cookie-cutter news and corporate propaganda that's produced elsewhere," said Sen. Bill Nelson, a Florida Democrat.

The FCC previously granted exceptions for companies such as News Corp. to own both a newspaper and a radio or TV station in the same market. Scrapping the rule would let more companies do so without needing to make the case for an exception.

The FCC is also loosening restrictions on one company owning two TV stations in the same market. TV station owner Sinclair is expected to benefit from these changes. It has a pending deal for rival Tribune Media that regulators still must clear. They both own TV stations that air local news and programming from the major networks, ABC, CBS, NBC and Fox, around the country.
