Havas’ Arnold last week landed Bob’s Stores’ $3-5 million broadcast creative account, the client said. Arnold’s New York office bested three other finalists: IPG’s Hill, Holliday, Connors, Cosmopulos in Boston; and independents North Castle Partners in Stamford, Conn., and Tucker Hampel Stefanides & Partners in New York. Bob’s formerly worked with Boston-based independent Clarke Goward. Hill, Holliday handles media, which was unaffected. Consultancy Pile and Co. in Boston managed the process.
