DVDs pretty quickly got the front-end trailers that were unskippable, though often fast-forwardable. The ad aspect hasn’t really changed. Cutting out the credits is such bullshit though. I’m not pretending I read them, but I want that time to process the ending of a movie set to the song(s) picked for the ending. Getting immediately thrown into a bright peppy ad after a dark ending is so obnoxious.
