The Tata Global Beverages brand called the review at the beginning of the month. It is being led by Adrian Mooney, who was appointed vice-president of marketing for the UK, Ireland and South Africa in September last year, in partnership with intermediaries Oystercatchers and TradeMark Management.
Mooney has previously worked with Walker Media during a stint as the interim marketing manager at cereal brand Weetabix, one of the agency's clients.
At the time of calling the review, Mooney said: "We have some exciting plans for 2012 and finding the right media agency partner in this process will help execute those in the most creative and cost-effective way.
MediaCom's sister agencies Maxus, Mindshare and MEC are understood to have been involved in earlier chemistry meetings.
Creative duties on the Tetley brand are handled by Dare, which is unaffected by the review of its media account.
The Tetley brand was acquired by Tata Global Beverages in 2000 for £271m from Schroder Ventures and PPM Ventures, the private equity firms.
