Definition: YouTube


The largest video sharing site. Allowing anyone to upload videos for private or public viewing, YouTube is the second most visited site on the Web (Google search is the first). YouTube delivers more video hours than all the major streaming services combined.

Founded in 2005 by Chad Hurley, Steve Chen and Jawed Karim, YouTube was acquired by Google in 2006 for $1.65 billion. Within a couple years, YouTube was streaming 25 petabytes (quadrillion bytes) of content each month.

Providing a venue for sharing videos among friends and family as well as a showcase for new videographers, YouTube instructional videos are available on every subject on the planet. It is also a destination for anyone who wants to make a statement. By embedding the appropriate link in a blog or website, YouTube videos are activated from millions of venues.
