Los Angeles-based online video sharing web site Revver said Tuesday evening that it is adding new, impression-based advertising products available to its advertisers and content owners this month. The new advertising options, which includes pre-roll and post-roll video ads, come as an expansion on the firm's current cost-per-click advertising. Revver said that content owners will be able to choose whether they'd like to use CPC or CPM-based advertising. Revver provides an online video sharing site which splits advertising revenues with content creators. The firm is venture backed by Draper Fisher Jurvetson, Bessemer Venture Partners, Draper Richards, along with Comcast Interactive Capital and Turner Broadcasting.
