ELI5: Why is there a gap between when a film comes out in the cinema and when it comes out on DVD?

Major studios make deals with theaters that they won't release a film onto home distribution for X weeks so that the theaters can make money off of it.

Then they make sure that cable doesn't get access to them for X more weeks so that the home video/redbox gets to make more money off of it.

Independent movies that don't have this big distribution channel will frequently release their movies into a small number of theaters and also to VoD on the same day.
