And as streaming services continue to gain favor over traditional TV, media firms are likely happy to oblige, helping further industry consolidation. Film studios without their own streaming service are especially keen on finding a way to get eyeballs on - and monetize - their libraries.

Disney even offers a $13.99 $4 that includes Disney+, Hulu, and ESPN+.

Netflix announced a deal with Sony in April

The agreement will allow $4 in the US, including installments of the "Spider-Man" franchise with Tom Holland. Other potential future Sony releases could include "Jumanji" and "Ghostbusters."

$4 starring Anthony Hopkins, "Rocky," and the extensive James Bond film catalog. Although as Insider's Travis Clark reported, $4, with the rest belonging to producers that handle the creative direction of the franchise. That means that it could get tricky if Amazon ever wanted to, say, produce a TV series starring the famous character.
