I just looked it up because I have no idea how big the music industry is, and…
US$26.2 billion globally in 2022 according to IFPI, and US$31.2 billion according to Statista.
Other than Netflix, I think FAANG just doesn't care that much about such a small market (the market being "actually producing it", given they're already part of the previous numbers for selling and streaming it).
And of course, both A's and the N of FAANG have their own commissioned TV/film content.
