True, but Streaming also benefits from new releases based on Broadcast TV.Seasons were only longer due to wanting to build up a syndication package to sell to affiliates down the line. That's not really a priority anymore because streaming is a completely different system. Broadcasting NEEDS content to air at all times, whereas streaming is just an on demand function.
And I don't think Broadcast TV will ever go away, it'll still exist like Radio has.
We can be like "The French" and have regulated priority order with Broadcast getting initial release, then Streaming can be "Next Day", etc.
