Pretty Famous:
PrettyFamous, an entertainment research site by Graphiq, found the most famous band formed each year since 1951. To do this, they created a customized Band Score on a scale of 1 to 100 based on a weighted average of a band’s Wikipedia page views in the last 30 days, page views of album releases and total number of Spotify followers.
The bands with the highest Band Score from each year were then ordered into a list starting in 1951 and continuing to 2015. It is important to note that since Wikipedia page views are current, all of these bands have stood the test of time, and remained famous many years after they were formed.
Interesting methodology. Not sure how you’d come up with a better measure of fame without turning straight to sales numbers.
Regardless, I found this pretty interesting. Scroll down to the tool, type in a year, then start clicking the arrow just to the right of the band picture to step through other bands formed in that year.
