<P> One development occurred in mid 2013, when billionaire Jeff Bezos, founder of Amazon.com, paid US $250 million for The Washington Post and several smaller newspapers . (The Post company had sold Newsweek a few years earlier .) The purchase, which ended the more than 80 - year ownership of the paper by the Graham family, was called "generous" by publisher Katharine Weymouth, who was asked to remain at the helm . When it was noted that the paper might have to run stories which are critical of Amazon.com or Bezos in the future, Bezos agreed not to interfere with the newspaper's independence . Others have said that Bezos drastically overpaid for the paper, and that late publisher Katharine Graham might not have made the sale . </P> <P> The deterioration in the United States newspaper market led one senator to introduce a bill in March 2009 allowing newspaper companies to restructure as nonprofit corporations with an array of tax breaks . The Newspaper Revitalization Act would allow newspapers to operate as nonprofits similar to public broadcasting companies, barring them from making political endorsements . </P> <P> A 2015 report from the Brookings Institution shows that the number of newspapers per hundred million population fell from 1,200 (in 1945) to 400 in 2014 . Over that same period, circulation per capita declined from 35 percent in the mid-1940s to under 15 percent . The number of newspaper journalists has decreased from 43,000 in 1978 to 33,000 in 2015 . Other traditional news media have also suffered . Since 1980 the television networks have lost half their audience for evening newscasts; the audience for radio news has shrunk by 40% . </P> <Table> <Tr> <Td> </Td> <Td> This section needs to be updated .
