I've been wondering for awhile how Google gets away with their anticompetitive practices in terms of YouTube. They built a huge business on search advertising, and then turn around and use that to run a video distribution infrastructure for well over a decade at profound economic loss just to guarantee no one else could ever get investment to build a competing infrastructure. It's essentially impossible to get the billions of dollars necessary to build a global video distribution system if you have to tell investors that they need to be willing to lose mountains of money for perhaps multiple decades while they wait out Google.
