> Video streaming services like Netflix are a joke in comparison.
Netflix realised quite rapidly that it was a fools errand to try to have everything.
Given the choice between paying top dollar for every blockbuster film (which engage people for two hours at a time), Netflix invested in TV series and producing its own material, which works out cheaper and keeps people watching for much much longer. Netflix's movie catalogue has shrunk since 2010 (mostly due to Epix moving its films over to Hulu), but the TV inventory has tripled.
Netflix also benefits from TV/movies being more fungible, and with a better long tail than music. If Netflix doesn't have a TV show or movie, you'll likely find something else you want to watch. If Spotify doesn't have Taylor Swift, it doesn't have Taylor Swift.
