Watching TV on a tablet will soon be included in official viewing figures, it has been confirmed.
The Broadcasters' Audience Research Board (Barb) announced that, with advisory firm Kantar Media, it has developed a new measurement technique to include people watching on a tablet PC.
The two companies claim this is the first industry solution to electronically monitor how many people watch TV on these devices.
At first, Barb will focus on selected homes that already have a software meter that tracks viewing on laptops and PCs. It predicts about half of these households will have tablets.
The technology was first tried in August, when a panellist watched an episode of 'Guy Martin's Passion for Life' using the 4oD app on his iPad.
Barb will publish its data in the coming months.
It's estimated that 2% of all TV viewing is done online through computer devices.
Jonathan Allan, sales director of Channel 4, said: "This is fantastic news because of the extremely rapid rate at which tablets have become part of our daily lives. UK broadcasters have developed compelling apps for our viewers to watch their favourite live and on-demand programmes.
"We're delighted that Barb and Kantar have overcome research and technical challenges to deliver this solution and look forward to using the insights they generate."
Justin Sampson, chief executive of Barb, added that it was a "great step forward", and said that it plans to accelerate deployment in its panel of software meters that track viewing on laptops, desktops, and tablet computers.
