It seems to be based on this maybe? https://www.datanyze.com/market-share/online-video--12/youtube-vs-vimeo https://www.datanyze.com/market-share/online-video--12/youtu... Apparently YouTube has 2,485,221 "websites" and Vimeo has 624,352. I have no idea what a website is in Datanyze parlance and can't find anything on their website that explains it. I'm also not sure what the pie chart is which seems to suggest they only have half the market between them while their market shares add up to 92.28%.
