Britons increasing appetite for watching video content on computers, tablets and mobile phones helped drive digital advertising spend up 16.6% to a record £3.5 billion in the first half of 2014 – according to the latest Internet Advertising Bureau UK Digital Adspend report, conducted by PwC.
Video advertising on the internet and mobile phones grew by 59% year-on-year to £202 million in the first half of 2014. Mobile video advertising, alone, grew 196% to £63.9 million and is now the fastest growing digital ad format.
Accompanying online YouGov data reveals 73%¹ of Britons online who own an internet-enabled device watched TV programmes online in the last six months, 72% watched short online video clips and 59% watched films online. Those watching TV online average 2 hours 35 minutes¹ a week doing so, compared to 1 hour 50 minutes for online film viewers and 51 minutes for video clip viewers.
“A third of online viewers, particularly 35-44 year olds, are watching more TV, films and clips online than a year ago. Consequently, video now accounts for £1 in every £5 spent on internet and mobile display ads,” says Tim Elkington, Chief Strategy Officer at the UK’s Internet Advertising Bureau. “Average weekly viewing online amounts to 25 videos, 4-5 TV episodes and one film but what's most interesting is that watching video on connected devices is becoming an increasingly social activity, like traditional TV. Half of people watching TV, films or video clips online do so with family members and three in ten watch with friends."
Device owners in Scotland are the most likely to watch TV (78%)¹, films (66%) and video clips (82%) online. However, among online TV and film viewers, those in London average the most time online watching TV (3 hours 6 minutes per week) and films (2 hrs 27 mins) each week. Among video clip viewers, people in the south average the most time (1 hr 2 mins).
