Including Google Video. Google did try the tactic of using their search engine to promote their own video platform, but it was against YouTube and Google only bought them because it didn’t work.
Plus the early days of google (before youtube acquisition), i dont think their video search was as good as the text search anyway (but i might be misremembering of course...).
The video results for most of my queries are like 90% SEO garbage without a video even being present on the linked page.
It's abject failure.
