Durinng the television generation, live boxing lost popularity and was replaced by sports that were more aesthtically pleasing

Boxing

Explanation:

Before the television generation, boxing was regarded as one of the most popular sports in the US. However, boxing lost its appeal for TV networks and watchers because of the brutality of the sport.

One of the main events that turned this around was a match from 1982. between Ray "Boom Boom" Mancini and Duk Koo Kim, after which the latter died. The tragedy made networks reconsider broadcasting of the sport that was perceived as brutal, and potentially fatal. As a result, boxing stopped being broadcast on the major TV networks in the States.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
