Newer videos uploaded to YouTube allow users to choose between 360p, 480p, 720p and full High Definition (or 1080p). You may be asking yourself what do those numbers mean to me?
To clarify, 1080 represents 1, 080 lines of vertical resolution with 1920 pixels on each line (Clark, 2006, para. 5).
The following are links to the same video encoded in the aforementioned resolutions. *Please note the high quality versions require a broadband, or high speed, Internet connection in order to be properly viewed.

- http://www.youtube.com/watch?gl=DE&hl=de&v=ngWtusnU8fI&fmt=18 (480p)
- http://www.youtube.com/watch?gl=DE&hl=de&v=ngWtusnU8fI&fmt=22 (720p)
- http://www.youtube.com/watch?gl=DE&hl=de&v=ngWtusnU8fI&fmt=37 (1080p)
For example, this is the first video ever uploaded to YouTube in 2005: http://www.youtube.com/watch?v=jNQXAC9IVRw
Users do not have the option to alter the resolution; however, users can manually add &fmt=18 at the end of the video to view it in 480p: http://www.youtube.com/watch?v=jNQXAC9IVRw&fmt=18
Furthermore, adding &fmt22 or &fmt=37 at the end of the link will not increase the resolution as the original source video was not recorded in either resolution.
Personally, I typically add the &fmt= codes to music videos to improve the song quality while web surfing.
Enjoy.
