DW COMPUTER CENTERS INC., Vernon Hills, IL, plans to launch a multifaceted branding campaign. While CDW is supporting this strategic changeover with an overall commitment of $85 million through 1999, the company has not yet determined how it will specifically allocate marketing dollars and to which media, said newly named public relations manager Ann Fahey-Widman. CDW signed Atlanta shop Donino, White & Partners to develop this campaign. In addition to the advertising component, CDW said it will integrate its branding message into all marketing and communications vehicles.
