Joseph Turow summarizes how marketers are using new technologies to make it "harder than ever for audiences to escape, and resist, their advances." One practice, "seeding," blends "publicity, product placement [3], and public relations." Seeding can involve hiring actors for "clandestine campaigns that 'may consist of seeding chat rooms, blogs and forums with paid-for messages,'" as one marketer explained. A Weber Shandwick executive described the goal as to "enlist, equip and harness the power of trusted, informed and credible messengers." Another tool, "behavioral targeting," allows marketers to customize online ads, depending on Web pages visited and searches performed. Soon, "registration data, your movements on their site, and even information about you that they've purchased from a third party" will also be available to marketers. Offline examples of behavioral targeting include customizable cable TV commercials and convenience store coupons.
