WASHINGTON, Oct 25 (Reuters) - The U.S. Federal Communications Commission wants to rollback landmark media ownership regulations that limit the ability of companies to own multiple TV stations and newspapers in the same market, Chairman Ajit Pai told a congressional panel Wednesday.
If approved at the FCC's November meeting, the move would be a win for newspapers and broadcasters that have pushed for the change for decades, but was criticized by Democrats who said it could usher in a new era of media consolidation.
The FCC in 1975 banned cross-ownership of a newspaper and broadcast station in the same market, unless it granted a waiver, to ensure a diversity of opinions. The rule was made before the explosion of internet and cable news and Republican President Donald Trump and Pai have vowed to reduce government regulation.
"We must stop the federal government from intervening in the news business," Pai said, noting that many newspapers have closed and many radio and TV stations are struggling. Pai moved earlier this year to make it easier for some companies to own a larger number of local stations.
Pai said the marketplace no longer justifies the rules, citing Facebook Inc and Alphabet Inc's dominance of internet advertising.
"Online competition for the collection and distribution of news is greater than ever. And just two internet companies claim 100 percent of recent online advertising growth; indeed, their digital ad revenue this year alone will be greater than the market cap of the entire broadcasting industry," Pai said.
FCC Commissioner Mignon Clyburn, a Democrat, said at the hearing Wednesday the move would lead to further consolidation in the media business and should be opposed. There are three Republicans and two Democrats on the panel.
Pai also proposes to make it easier for companies to own multiple TV and radio stations in the same market.
The National Association of Broadcasters said in a statement it backs Pai's plan, noting that policymakers have approved numerous "mega-mergers" among phone, cable and satellite programmers "while at the same time blocking broadcast/newspaper or radio/TV combinations in single markets."
The group added "this nonsensical regulatory approach has harmed the economic underpinning of newspapers, reduced local journalism jobs, and punished free and local broadcasters at the expense of our pay TV and radio competitors." (Reporting by David Shepardson; Editing by Lisa Shumaker)
