Entertainment Tonight/YMMV

Dork Age: When the show switched from vapid entertainment news and hype to vapid reality TV and sensationalist tabloid stuff and blind rumors (once the Hard Copy staff moved over to ET).
Too Good to Last: ET actually had dismal ratings in its first season and was only able to stay on the air because it was the first syndicated show to be offered via satellite, which meant that stations airing the program could air it in any time slot they wanted. Earlier syndicated programs, even those that were higher rated, did not enjoy such luxuries, and instead, their master tapes would get "bicycled" around from station to station, and thus they could not be aired as often as their network counterparts. It probably also helped, however, that Paramount Television president Richard Frank was a former protege of Alfred Masini.
