It is my understanding that in social media platforms, there are 3 primary players:

1. Users - The Users come for content from Content Creators.
2. Content Creators - The Content Creators come for revenue from the Advertisers.
3. Advertisers - The Advertisers come for views from the Users.

If any one of these is missing, it is impossible to reproduce a platform like Facebook, YouTube, or Twitter. I would very much like to build my own social media platform, but I cannot find a module where advertisers can purchase and submit their ads, and where I have a way to run those ads in users' feeds or while they watch videos.
