"The U.K. online video market continues to soar and is attracting a
greater and greater share of Internet users' attention," said Mike Read, SVP
and Managing Director, comScore Europe. "In particular, we've seen eyeballs
move towards the online channel to watch more long-form, professional video
content, such as popular broadcast network TV shows. This trend presents a
significant opportunity to advertisers, as comScore research has consistently
shown that online video advertising is effective at building brands."

Channel 4's Young Audience Consumes Highest Number of Videos per Viewer

The online video viewing audience at the sites of the U.K.'s leading TV
stations exhibit significantly different skews by age and gender. While the
BBC's video viewing audience tends to be male (index of 110) and spread
between the ages of 25 and 54, Channel 4 skews heavily toward the 15-24 year
old age group with an index of 154. The site was visited evenly by males and
females but women watched five more videos (21.7) than male viewers on the
site during the month. ITV Sites had the least appeal to males (index 84) and
captured a larger proportion of female viewers of all three sites (index
119).
