Now the 300×250 banner can show video ads, including those from display campaigns in Yandex.Direct. This new addition will be especially useful for owners of mobile sites interested in expanding their audiences and making additional profit. You get the chance to find more customers on both smartphones and tablets. Users, on the other hand, get to see more relevant, targeted ads that can lead them to products and services they are interested in.
Video is added automatically to 300×300 and 300×250 banner blocks. It is enabled by default, but you can untick the box in the YAN partner interface to stop video from appearing in your banners. You don't need to update your SDK version if you already use SDK for iOS version 2.8.3 and SDK for Android 2.7.3.
