The 2011 MTV Video Music Awards dominated Twitter and YouTube in the Pew Research Center’s Project for Excellence in Journalism’s New Media Index for the week of Aug. 29-Sept. 2, while bloggers focused on a much more serious event in Hurricane Irene.

The annual MTV extravaganza was the topic of the most news links shared via Twitter for the week, followed by: Korean boy band Super Junior; suggestions on how to use Facebook; the upcoming iPhone 5; and an interactive timeline of the evolution of the Web, created by members of the Google Chrome team.

The most-viewed news and politics videos on YouTube were VMAs highlights, followed by: Spanish-language footage of a fatal arson attack on a casino in Monterrey, Mexico, Aug. 26; NASA images of Hurricane Irene from space, including a UFO sighting between the International Space Station and the hurricane; a Russian-language parody about the Russian presidential elections; and an Associated Press Irene update from Aug. 27.

Irene’s grip held firm on the list of most shared news links by bloggers, followed by: the 2012 presidential campaign, particularly Republican candidate and Texas Gov. Rick Perry; the iPhone 5; the VMAs; and the Samsung Galaxy S II LTE phone.
