A Wesleyan Media Project report finds that 2010 was a record-breaking year for campaign advertising: 1.6 million airings in congressional elections, which is a 36% increase over 2008, at an estimated cost of $735 million. The reasons: “There were an unusual number of competitive races for Congress — and an unusual number of incumbent party losses. Recent Supreme Court decisions opened up new sources of funding for advertising in these contests, which may (or may not) have contributed to the record volume of ads and ad spending in federal races. Moreover, advertising in the 2010 elections was record-setting in its negativity, at least when compared to other federal races in the past decade.”
