A new study lists the most memorable TV moments of the past 50 years. Sony Electronics and the Nielsen Television Research Company conducted the survey.
According to the study, the September 11 terrorist attacks ranked the most memorable television moment. The second ranked moment was the coverage of Hurricane Katrina. O.J. Simpson's murder trial ranked third, followed by the Challenger Space Shuttle Explosion, and the death of Osama Bin Laden.
The study ranked TV moments for their impact by asking people if they remembered watching them, if they remember where they watched it, who they were with, and whether they talked to others about what they saw.
