The increase sees Turner Kids’ overall share of viewing to commercial kids channels boosted to 29 per cent, according to Barb figures.
Cartoon Network has also become the number one commercial channel for boys aged four to nine in the UK.
The channel has grown its ratings for this audience by seven per cent year-on-year, an increase largely attributed to the new series of Ben 10 Alien Force and Star Wars: The Clone Wars.
In turn, Boomerang has taken a strong share of the overall increase in girls’ TV viewing, up by 52 per cent year-on-year.
The firm is putting this growth down to the success of shows such as the new CGI series of Garfield, films like Garfield The Movie and Willy Wonka and the Chocolate Factory, as well as a rise in viewing of perennial favourites Scooby-Doo and Tom & Jerry.
Cartoonito, Turner Broadcasting’s dedicated pre-school channel, which airs on Sky 619, had the biggest combined growth for girls and boys, pulling in an additional 33 per cent audience year-on-year.
The new series of Fireman Sam, Hi-5 and Go and Be a Grown Up has contributed to Cartoonito’s continued ratings growth.
Dee Forbes, SVP and GM, of Turner Broadcasting System UK and Ireland said: “This an excellent first half of the year, showing a robust performance from all our channels. In a highly competitive market, which sees decline for our competitors, Turner Kids continues to go from strength to strength.
“As well as excellent programme content, we’re bolstering audience and client relationships with multiplatform activity such as Incredikids on Cartoon Network and the inaugural Boomerang ‘Pet Personality Awards’ launching later this year.”
