Newspapers continue to outpace broadcasters and radio stations in the amount of local ad revenues placed on their Web sites, according to a study released last month by Borrell Associates.

The report, “What Local Media Web sites Earn: 2008 Survey,” stated that, on average, the local newspaper snared almost 12 percent of the online advertising market, while broadcasters and radio stations each captured less than a 1 percent market share.

The report analyzed Web revenues for more than 3,100 media properties, including 741 daily and 272 weekly newspapers, and found that overall local online revenues are growing at a rate of 50 percent this year. Borrell expects revenues from local online ads to reach $13.1 billion this  year, up slightly from the $12.6 billion the firm estimated in December 2007.
