Last week, WarnerMedia, the AT&T-owned parent company of Warner Bros. Entertainment Inc., announced that it would release all of its 2021 first-run movies to its streaming service, HBO Max, at the same time it releases them to theaters. This comes on the heels of reports that Disney’s Plus streaming service may do the same with all of its 2021 releases and is also considering a merger with Hulu to boost overall subscriber reach.This is huge: Two of the largest film studios are moving the balance — perhaps all — of their premium movie content to streaming platforms. The move represents a seismic shift in the entertainment industry that will forever change the way film and television is produced, monetized, and consumed.
