The Perez Hilton or TMZ of the time was Entertainment Tonight which premiered in 1981. It was the first modern daily tabloid show. It was so shocking at the time...now it seems so common the news format for gossip.

Yea there was a lot of newspaper gossip columnists, but that was old school newspaper world. ET with it's instant satellite program brought it to a new level.
I will never forget my HS history teacher at the time watch it one night and came into school the next day ranting and raving about how this was the downfall of society. From the editing to the content of the show. Trying to explain to us 14 year olds how the media was manipulating us. He really was perturbed by the possibility that this would become more commonplace. He must have been around 50 years old at the time. I remember a lot the adults being very fearful the world had changed way too much since their youth. I can't help comparing this to the first season of Mad Men which was set in 1960. 22 years later the world had change much more than it has from 1990 until today.
