The agency surveyed 570 children aged between seven and 14 years old for its 'Child Track' report to discover their favourite UK television ads, and 33% voted for the Crazy Frog ringtone spots that have been irritating adults for months.
KFC slipped into second place, with 8% of kids admitting they love the spots with call centre workers singing with their mouths full, as created by Bartle Bogle Hegarty.
The ads that are the most talked about are the one the children love best. According to the latest Ads that Make News survey by media industry PR specialist Propeller Communications and Durrants Media Monitoring, Jamster's Crazy Frog and KFC were the two most-written about ads last month.
Other ads to make it into the top five of 'Child Track' report were fellow Jamster characters Nessie the Dragon and Sweetie the Chick, coming joint third with 5% each and McDonald's fifth with 4%.
Walkers Crisps, Adidas, Coca-Cola/Diet Coke, Kandoo and car ads also made the top 10.
Carrick James, managing director of CJMR, said its monthly 'Child Track' survey will continue to monitor the longevity of the Crazy Frog ads.
"We have long seen crazes come and go but we are particularly interested in how long this one will last and what else will be replaced with," James said.
The ad has racked up more than 800 complaints to the Advertising Standards Authority and the Crazy Fog theme tune to 'Beverly Hills Cop' by Axel F managed to keep Coldplay off the number one chart position for two weeks in June.
