SAN FRANCISCO, Sept. 19, 2011 /PRNewswire/ -- Esurance, the direct-to-consumer personal car insurance company, today named Leo Burnett as its new advertising agency of record. (Logo: http://photos.prnewswire.com/prnh/20090826/ESURANCELOGO) Leo Burnett Chicago won the Esurance business after a rigorous selection process that also included Deutsch LA; Duncan/Channon; Goodby Silverstein & Partners; and Venables Bell & Partners. "The decision was a difficult one for us, since all five agencies presented amazing work. Ultimately, we felt that Leo Burnett delivered the best option for continuing the development of Esurance's brand voice in a crowded industry," said Esurance Chief Marketing Officer John Swigart. The relationship will be managed from Leo Burnett's Chicago office, which will begin working immediately on a new advertising campaign. In May 2011, White Mountains Insurance Group, Ltd. announced that it had signed a definitive agreement to sell Esurance and Answer Financial to The Allstate Corporation, the nation's largest publicly held personal lines insurer. The transaction is subject to regulatory and other customary closing conditions, including review by antitrust authorities and state regulators and is expected to close in the fall of 2011. Following the closing, Allstate has indicated that the Esurance and Allstate brands will remain distinct, with each company serving a separate target segment with a different value proposition. Esurance focuses on consumers who prefer to shop for and buy car insurance online. Leo Burnett, which has been the longtime ad agency for Allstate, will service Esurance with a separate team.
