Nielsen and Sony teamed up to determine what were the most impactful moments ever show on television. I think this is an age thing. The winner was by far 9/11 followed by Katrina and OJ. People who were around in 1963 also picked the assassination of JFK. I would say that 9/11 wins just because so many people watched it live and then we watched it over and over. The OJ chase was interesting, but I'm not sure how impactful it was. What do you think was the most impactful moment on television?
