MuchMusic is a Canadian television station that started out as a television station dedicated to music in the 80's and would primarily play music videos nearly all the time. Inbetween the music videos it would play some shows with interviews from the artists creating the music and exploring new music genres being invented etc. There was much to do with music on it.
Sadly, somewhere in the late 90's or 2000's the format changed and it started playing anything but music videos and shows related to music. It really should be called "Not Much Music" now. It also has a spin-off channel "Much More" which should really be called "Much Less Music" because it doesn't seem to play any shows related to music on it anymore either.
Granddaughter: Hey, grandpa do you want to come watch Twilight with me, it's on MuchMusic.
Grandpa: Nah, my love. When I was a wee little lad I remember the days when I could turn on MuchMusic and see such great videos as A-Ha's Take On Me, Princes When Doves Cry, Duran Duran's Hungry Like The Wolf and The Police's Every Breath You Take. These days I prefer to remember it in it's glory days when it lived up to it's name "MuchMusic". These days they should really rename it "NotMuchMusic" because it has become to music just about what the History Channel has now become to History.
