The term video advertising encompasses online display advertisements such as Mid-Page Units (MPUs) that have video within them, but it is generally accepted[by whom?] that it refers to advertising that occurs on Internet television. It is served before, during and/or after a video stream on the internet.
The advertising units used in this instance are pre-roll, mid-roll, and post-roll and all of these ad units are like the traditional spot advertising you see on television, although often they are "cut-down" to be a shorter version than their TV counterparts if they are run online.
Broadcast websites such as Sky.com and itv.com have such advertising on their sites, as do newspaper websites such as The Telegraph, and The Guardian. In 2010, video ads accounted for 12.8% of all videos viewed and 1.2% of all minutes spent viewing video online.
