YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, who were all early employees of PayPal. Hurley had studied design at Indiana University of Pennsylvania, while Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign.

The company is based in San Bruno, California, and uses Adobe Flash Video technology to display a wide variety of user-generated video content, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos. Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, BBC, Vevo and other organizations offer some of their material via the site, as part of the YouTube partnership program.

Effective January 10, 2011, YouTube locked out all registered users who declined to merge their accounts with a Google account. New registrations without the linking of a Google account had been prohibited since 2009.

However, I found many people want to know how to upload DVD to YouTube Mac as below.

Q1: Does anyone know how to get a DVD onto a YouTube video? I have a Mac?
I got the Mac the ripper application, but it doesn’t do anything for me. I just want to put my DVD file into a YouTube video. I made the video, so this is NOT illegal.

Q2: Is there any way to convert a DVD to YouTube?
I have this DVD that my friends and I made, and we want to put it on YouTube. I put the disk in and it plays, but I can’t save it as a movie. Is there any possible way to save it as something else that allows me to put it on the site? Please help!
Btw this is being done on a Mac if that means anything

For resolving these problems, I search a tool--- DVD to YouTube Converter Mac in the website. Mac DVD to YouTube Converter can help you convert protected or unprotected DVDs to FLV, MOV, MPEG-4 accepted by YouTube, with no quality loss and high-speed conversion. I hope it is helpful for us.
