Coverage of gay marriage continues to dominate the conversation online but is being roundly ignored by traditional offline media sources, according to newly released New Media Index figures by the Pew Research Center's Project for Excellence in Journalism.

The index found that gay marriage was the number 1 story being discussed online during the week of May 25 to 29. The California Supreme Court's ruling last week upholding the constitutionality of a gay marriage ban amassed a whopping 35% of all linked-to stories by bloggers and social media

But traditional media brushed off the gay marriage debate, devoting 24% of its newshole to President Obama's nomination of Supreme Court Justice Sonia Sotomayor instead, and short changing the gay marriage issue with only 5% of their coverage.

“That disparity in coverage illustrates a basic difference between the traditional media's more hierarchical structure and the online world's self-motivating communities of interest,” researchers said in reporting their findings.

Interest in gay marriage has dominated the blogosphere over the past two months – coming in first or second place each week – starting with the trifecta win of Iowa, Vermont and the District of Columbia in early April.
