YouTube was founded on February 14, 2005, by Chad Hurley, Jawed Karim, and Steve Chen. The three former PayPal employees created the site as a way to share videos they had taken of themselves at the San Diego Zoo. The name 'YouTube' was coined by Chen and Karim, who were inspired by the fact that a lot of people were using the then-new website 'to share and upload videos.'

The first YouTube video, 'Me at the zoo,' was uploaded on April 23, 2005, and shows co-founder Jawed Karim at the San Diego Zoo. The site began as a way for people to share personal videos, but quickly became a popular destination for user-generated content, including music videos, TV clips, and home movies. The headquarters of YouTube are in San Bruno, California.
