Criticized for not putting enough marketing push behind its "Anyway You Want" options for renting movies and video games, Blockbuster said Thursday that it will launch an ad campaign on TV and radio describing how its customers enjoy the convenience of using the Internet, kiosks, the mail -- or the old-fashioned "big blue" stores -- when they deal with the company, alternatives that no other company offers. As reported by Home Media Retail magazine, Blockbuster chief Jim Keyes appeared to acknowledge in an address to shareholders Thursday that consumers are slowly making the transition to electronic rentals. "We still do have the largest share of the consumers, and it is our job to make that transition [from physical to digital] for the consumer easy, seamless and virtually invisible," Keyes told the investors.
