When you have a movie as big as Guardians the Galaxy 2, it’s going to have some unexpected effects. One such effect in 2017 was the rise in sales cassette tapes, which saw a significant boost 35%.


However, these are still cassette tapes we’re talking about, and while a 35% boost in sales is no small feat, the medium still accounts for “less than one-half one percent all album sales in the U.S.,” according to Forbes. Only 174,000 cassette albums were purchased in America last year.

Forbes goes on to say that 22% all cassette sales in the U.S. in 2017 are directly attributable to Guardians, which has two film and one TV show soundtrack included on the Nielsen year-end report.
