Growth in the Duration of the Mean Web Video
The duration of the mean web video has grown significantly since 1997. In 1997 the length of the mean web video was a mere 45 seconds long (Acharya & Smith 1998). In 2003 the mean web video grew to about 120 seconds long, or 2 minutes (Li et al. 2005). By 2007, the median video was 192.6 seconds in duration (Gill et al. 2007). In 2010 the mean web video was 270 seconds long in duration (Karki 2011). Meanwhile, the bitrate and dimensions of the mean web video has grown from 200Kbps in 2003 to 300Kbps in 2010.
