At it's peak, Black's video was seen 4.6 million times in one day.
Black's "Friday" was posted in February and became a web phenomenon in March.
And what a phenomenon it was. "Friday" racked up 100 million views in just roughly a month, which was faster than Justin Bieber accomplished it. As we pointed out, the fact that her first video was about a day of the week actually ended up being a contributing factor to that video's staying power.
