YouTube was bought by Google last year. The search engine has started showing YouTube in the search results of Google Video. Google blog has reported that, “Google search results already include links to content that's hosted on YouTube. Starting today, YouTube video results will appear in the Google Video search index: when you click on YouTube thumbnails, you will be taken to YouTube.com to experience the videos. Over time, Google Video will become even more comprehensive as it evolves into a service where you can search for the world's online video content, irrespective of where it may be hosted.”
Google has taken the step for providing users with search results of the highest quality. The post also elaborates that:
YouTube, as we've stated previously, will remain an independent subsidiary of Google, and will continue to operate separately. Google will support YouTube by providing access to search and monetization platforms and, when/where YouTube launches internationally, to international resources. YouTube co-founders Chad Hurley and Steve Chen and the rest of the YouTube team will continue to innovate exciting new ways for people to broadcast themselves.
