The MuchMusic Top 20 Countdown is a two-hour music video program block, that airs on Canadian music television station MuchMusic. Countdown is one of the oldest programs that continues to be aired on MuchMusic since its debut. Originally sponsored by Coca-Cola, it was known for the first several years as the Coca-Cola Countdown.
The program airs a playlist of the most well-known songs in the mainstream. The order that the videos are played goes from No. 20 to No. 1, although only about 10-12 of those videos are actually played. Most of the videos that go unplayed are older videos that are fading off the chart, or less popular videos. A video that is moving down the chart or is in the same spot as that previous week will in general not get played. Every video debuting on the chart is played. A music video that reaches the No. 1 spot usually stays there for 1–2 weeks.
Here is a listing of number ones from 1996 onwards:
