"Smartphone owners are clearly driving the mobile video trend, an
indication that more growth is on the horizon as an increasing number of
smartphones hit the market," Mr. Copp continued. "We've also seen that recent
releases such as Apple's iPad and Samsung's Galaxy Tab are designed to offer
an incredible video experience, and when coupled with services such as the
BBC iPlayer for mobile, make this an extremely interesting sector to watch."
