Sales double for Rolling Stone bomb suspect cover

After Rolling Stone sparked a public outcry for featuring the surviving Boston Marathon bombing suspect on its cover earlier this month, several major retailers vowed not to sell the controversial issue.

Apparently that didn't hurt the magazine's sales. According to Adweek, the issue with Dzhokhar Tsarnaev on the cover has sold twice as many copies as an average issue.

The trade publication said more than 13,000 copies of the magazine were sold at more than 1,400 retailers from July 19 to July 29. That is more than double the magazine's average sales for the previous year, Adweek said.

Critics - including Boston Mayor Thomas Menino and Sen. John McCain -- accused the magazine of glamorizing terrorism.

A Facebook page -- Boycott Rolling Stone Magazine For Their Latest Cover - has generated more than 170,000 "likes."

Tsarnaev has pleaded not guilty to 30 federal charges including using a weapon of mass destruction to kill.

Earlier this month, Rolling Stone defended the story, saying it was part of its "longstanding commitment to serious and thoughtful coverage of the most important political and cultural issues of our day."
