Facebook is fast emerging as a more realistic alternative to YouTube for advertisers to spend the bulk of their video advertising budgets, according to a report. Video views on the social network are tipped to surpass two trillion this year, which is two-thirds of YouTube’s forecast total for the same period, according to Ampere Analysis. A sixth of Facebook video viewers have not watched YouTube in the last month, the survey of over 10,000 European and North American consumers revealed.
