Politico reports a study by the Wesleyan Media Project says a whopping 3 million ads ran during the election, which is up 33-percent from 2008.
They also found that 64% of the ads were negative, which is up from 51% in 2008.
The study also found that although both President Barack Obama and Republican presidential nominee Mitt Romney aired most of their ads during local news programming, the Obama campaign also bought significantly more air time on talk and reality shows and niche cable networks than the Romney campaign.
The Obama campaign continued to make efficient ad buys throughout the 2012 election. In all, Obama aired 2.5 times more ads than Romney, who paid more for fewer spots. Both campaigns spent heavily on advertising in Nevada and Colorado with Las Vegas and Denver media markets seeing the most presidential political advertising.
The amount of money spent on political advertising during the Republican presidential primary also skyrocketed in the 2012 election. Outside groups aired 60 percent of the total ads during the primary. In 2000, 2004 and 2008, less than 15 percent of all ads were aired by outside groups.
