The Internet and media fragmentation has killed virtually any chance of anything becoming a cultural phenomena and being ingrained into the public consciousness anymore.Streaming plus the explosion in genre based cable channels has fragmented the audience to a point that "communal TV" is practically dead. I can't tell you how long it's been since I've heard co-workers talking about a network TV show, or any TV show for that matter. The last "communal" show where almost my entire department (9 - with 7 of us watching by the end) were discussing episodes was Game of Thrones - and that wasn't on broadcast TV. As soon as that ended, so did our conversations about TV shows.
So nothing from this era will likely be remembered as much as even a flop from 30 years ago like Cop Rock.
