A new study by Nielson and Sony Electronics has compiled a list of the 20 most powerful moments in the history of television. Nielson surveyed 1077 American adults.

To measure impact, Nielsen and Sony created a score for each event derived by the number of people who viewed the event live, the number who could recall details about where they were during the occurrence and the number who could remember discussing what happened with others. Those parameters may explain why the surreal, slow-speed chase of O.J. Simpson's white Ford Bronco on June 17, 1994, ranked higher on the list than the 2011 earthquake in Japan, the Columbine High School shootings and the 2010 BP oil spill.
