What is Videos: Definition and 162 Discussions

YouTube is an American video-sharing website headquartered in San Bruno, California. Although the most-viewed videos were initially viral videos, such as "Evolution of Dance" and "Charlie Bit My Finger", the most-viewed videos were increasingly related to music videos. Since Lady Gaga's "Bad Romance" in 2009, every video that has reached the top of the "most-viewed YouTube videos" list has been a music video. Although some of the previously most-viewed videos are no longer listed on the site, reaching the top of the list is still considered a tremendous feat.
In November 2005, a Nike advertisement featuring Brazilian football player Ronaldinho became the first video to reach one million views.

    Visual Aids & Videos to Help You Learn Physics - Sanctioned by Physics Forums

And that's why I find videos so helpful. For example, I loved Carl Sagan's Cosmos series. His cosmic calendar is such...
