YouTube was created in 2005 by Steve Chen, Chad Hurley, and Jawed Karim as a platform for users to upload and share videos. It allows users to upload videos, view videos, comment on videos, and subscribe to other users' channels. While most content is uploaded by individuals, some media corporations also make content available through partnerships with YouTube. For content creators like the author, this means they can publish videos on YouTube where it can potentially be viewed by YouTube's massive audience.
