Really? The only way to educate users about other similar shows is to interrupt the viewing experience with intrusive ads?
If I like the video I am watching, I'm going to go to the creator's profile or channel or just click on one of the videos that appear after I've finished watching. Personally, I find these ads annoying and not effective. (I can't remember the last time I clicked on an in-video ad)
There seems to be this idea in marketing that if you promote yourself in a way that forces the user to be exposed to your message, you will be more effective and successful. The more effective companies, however, seem to focus on creating advertising that people want to see and create products that people like to use and will recommend.
