The new security measures implemented by the Transportation Security Administration dominated the list of news links shared by bloggers during the week of Nov. 22-26, while Mashable accounted for four of the five most-Tweeted news links, and the most-watched news and politics video on YouTube was a clip of a collision during an AC Milan soccer match, according to the Pew Research Center’s Project for Excellence in Journalism’s New Media Index.

A total of 54 percent of news links shared by bloggers were related to the controversy over the TSA measures — don’t touch my junk, bro — and it was followed by: Formula 1 racing, at 18 percent; British police, at 13 percent; a column in The Washington Post by former President Jimmy Carter about how the United States should handle relations with North Korea, at 4 percent; and also at 4 percent, news that Velma Hart — the woman who gained national attention at a September forum for telling President Barack Obama that she was exhausted defending him — lost her job due to financial cutbacks at the nonprofit organization where she worked.

The TSA brouhaha was the only non-Mashable entry in the top five news links shared by Twitter, coming in fourth at 9 percent. The most-Tweeted link was a report from the social-media news blog about ways people can use social media to enhance events and conferences, at 16 percent. It was followed by: a list of iPhone camera accessories, at 13 percent; a report on Rupert Murdoch‘s The Daily iPad-only news publication, at 12 percent; and, in fifth place, at 7 percent, two Twitter stories — one on its analytics service, and the other an interview with creative director Doug Bowman.

The AC Milan crash was followed on the list of most-viewed news and politics videos on YouTube by: an animated poke at the TSA controversy by Taiwan-based Next Media Animation; pundits on Fox News Watch sharing jokes about Sarah Palin‘s new TV show during a commercial break; the Nov. 16 installment of The Philip DeFranco Show; and a video from comedy group Die Aussenseiter.
