YouTube has become an invaluable resource for teachers and students since its inception a decade ago. YouTube, which is owned by Google, is now the second largest search engine in the world, with hundreds of millions of hours of video viewed every day on the website and 300 hours of video uploaded every minute to the site. Mesa Public Schools teachers and students have access to YouTube, and teachers have their own YouTube account, allowing them to subscribe to educational YouTube channels, and to create educational playlists for their students.
