A new study (PDF) from video monetizer FreeWheel has suggested that Apple devices may dominate mobile video viewing by a wide margin. Tracking across its five billion-plus video ads, it found that almost 80 percent of mobile video watching took place on an iPad, iPhone, or iPod touch, leaving Android 20 percent. The iPhone and iPod were joint leaders at 30 percent where the year-old iPad still matched the entire Android platform.
