MTV has been all over those "reality" shows and candidate shows since at least the late 90s though.
Hey, I'm Bam Magera and this is Jackass Roomraiders where Xibit builds flat screens into your entire house for no reason after we had a hot girl go through all your embarrassing shit while you waited in a car of some kind outside watching together with your adversaries who go absolutely apeshit about anything that happens, also UV sperm detection light.

Yep. Although it still did music videos for at least a few hours a day until the 2000s. VH1 was a holdout for a longer time. Does that Canadian MuchMusic channel even exist anymore? We got that when I used to have DirecTV. It had a fun early low budget MTV feel to it which I knew was not destined to last.
It was a fun channel. My favorite memory is having the lead singer of Barenaked Ladies come in and play foosball with the VJ. They said he could request any video he wanted, so he requested Mr. T's Commandments, which is an (I think unintentionally) hilarious video where Mr. T does a Christian rap about honoring your parents while beating people up.
MTV invented the reality format. The first few seasons of The Real World were innovative and novel. Then the execs realized how much cheaper reality was to produce and flooded the market with garbage until it was all we had left.
MTV's downfall started when they got rid of all the Music freaks in the C suite that liked music and hired TV producers. Then we got Remote Control. We didn't realize it at the time, but that was the downfall of MTV. Once those TV execs realized they could make non-music content, we got The Real World. It was OVER.
