Bryan Bresee tries to guess things from the 90's.
It's not age, it's a willful hubris that anything that happened before the year you were born is not worth your time to be concerned with.
Despite their popularity, I don't really consider any of those things really to be.all that relevant or memorable.
Yeah not even MC Hammer, sorry to say. He was on top of the world for about 2 years, then dropped off the face of the music scene altogether. His style of hip-hop was killed off rather quickly by NWA and its spinoffs (Ice Cube, Easy E, Dr. Dre) and then Death Row records/ Snoop Dogg, and was mostly forgotten except for the occasional laugh (along with Vanilla Ice). It was kinda like the early 90s equivalent of Styx in the late 70s, or the "Death To Disco" movement around 1980
I honestly do not remember Kid N' Play.
SBTB and 90210 were geared almost exclusively towards the YA crowd, which is incredibly fickle and has little inter-generational staying power.
The vast majority of sitcoms were basically forgetable. There are certain exceptions - like the All In The Family, The Brady Bunch, The Cosby Show, Leave It To Beaver, which persisted re-runs. If anything, Seinfeld was probably the more relevant sitcom of the 90s if anyone knows anything.
