OpenX Takes Aim at In-Banner Video, Aims to Block “Bad” Video Ad Formats from its Exchange

OpenX has announced today that it will begin blocking the sale of “bad” video ad formats from its exchange, including the 300×250 format, which it says provide a bad user experience and are harmful for brands and publishers. The company says it’s targeting the 300×250 format specifically due to its use in ad fraud, but other as-yet-unnamed formats will also be blocked.
