Blue Bell, Pa.--Fiberlink Communications Co., a specialist in providing secure Internet access to large companies, has launched a direct mail, print and Web campaign aimed at raising awareness for its corporate virtual private network services. Created by Hot Productions, Philadelphia, the campaign features Link Strong, a corporate road warrior conjured up for the ad blitz. A Dick Tracy lookalike, with a trench coat and fedora, Link Strong's adventures are featured on the company's Web site. In April, Fiberlink will follow its print advertising and Web blitz with a mailing to Fortune 2000 executives. Virtual Private Networks, or VPNs, are similar to standard Internet access, but feature enhanced security and guarantees of service not typically available to consumers. The budget for Fiberlink's campaign is $8 million.
