Showtime Networks announced a multimillion-dollar brand awareness campaign to run this summer from July 1 to Sept. 15, parallel to the release of the networks' new programming strategy. The campaign will be Showtime's most aggressive TV effort to date, according to Mark Greenberg, senior VP-marketing. In July, Showtime Networks will work with Eastman Kodak Co.'s Qualex unit to offer $10 rebates to Showtime subscribers who purchase prints from participating retailers; in August, 2,500 Blockbuster Video stores will post promotional banners for the network. An August Showtime Original Pictures sweepstakes will allow patrons of National Amusements theaters the chance at walk-on roles in a Showtime film. Locally, Showtime affiliates will use marketing tactics in connection with Showtime's "3-Day Weekend" such as direct mail, ad slicks and TV and radio spots.
