As more people upload videos, YouTube has seen a shift in subject matter. All categories saw declines in their share of the platform’s total content except for gaming, which is on a skyrocketing growth trajectory. Music content is the leading category in mutliple respects, recording 16,397 average views per video and 2,411 views per minute. It also includes the shortest average video length at 6.8 minutes. Pex notes that falling at those extremes means that music is some of YouTube’s most valuable content. It was responsible for about 20% of all views in 2018 despite being about 5% of all YouTube content, demonstrating a high return on investment.
