The ads look to improve people's perception of Ask Jeeves, which has developed new technology over the past few months to boost its service.
Two spots, showing on national terrestrial and satellite channels, aim to dramatise the key benefits of the service, from the range of questions it can answer to the improved accuracy of the results.
One execution, "zorbing", breaks on 1 November and opens on a hilly landscape with Jeeves "zorbing" along in a giant inflatable ball. A box appears reading: "What is zorbing?"
A second spot shows Jeeves holding a digital music player and dancing.
The Ask Jeeves search box reads: "Download music." The end frame on both ads reads: "Ask Jeeves. The find engine."
Aylin Savkan, the vice-president of marketing at Ask Jeeves, said: "We want to persuade online users to revisit Ask Jeeves to try out the improvements for themselves and these new animated ads help us put the message across that Ask Jeeves is a whole lot better."
The ads were written by Carol Haig and art directed by Phil Martin. They were directed by Bessey and Combe through Nexus Productions. Media planning and buying is through Media Planning Group.
