Surfing the Web without being fed ads seems more unlikely everyday, especially with the boom of online video. Whether it is pre-, mid- or post-roll, overlays or banner ads, substantial growth in online video ads means most people have seen one, even if they aren't aware.
Growth for online video advertising depends on the audience and the inventor--enough people to watch the ads and enough space to encourage mass marketers to buy the ads.
With 66.8 percent of all U.S. Internet users viewing some form of video advertising (in-stream, in-banner or in-text) at least once a month in 2008, the audience has reached critical mass.
According to eMarketer, by 2012 four out of five U.S. Internet users will view video ads--not surprising, since such ads will be ubiquitous by then.
That 66.8 percent share equates to 129.5 million people who will view online video ads this year. That figure is projected to rise over the next five years to 183.3 million viewers in 2013.
