Coming to a store near you: Bob Marley video games, shoes ... snowboards? Heirs of the Jamaican reggae legend are plunging into the global trademark wars, seeking to enforce their exclusive rights to an image that has grown steadily in scope and appeal since the Jamaican superstar died of brain cancer in 1981 at age 36. The Marley name, look and sound are estimated to generate an estimated $600 million a year in sales of unlicensed wares. Legal sales are much smaller - just $4 million for his descendants in 2007, according to Forbes magazine. The Marleys refuse to give a figure. Now the family has hired Toronto-based Hilco Consumer Capital to protect their rights to the brand. Hilco CEO Jamie Salter believes Marley products could be a $1 billion business in a few years. The turn to big business has stirred some grousing from die-hard fans in Internet chat rooms, who say it goes against the grain of a singer who preached nonmaterialism and popularized the Rastafarian credo of oneness with nature and marijuana consumption as a sacrament. Marley's lyrics promoting social justice made him an icon. Most of Marley's heirs are also musicians, including his widow, Rita, and son Ziggy, who won four Grammys with the Melody Makers, a band that included son, Stephen, and daughters Sharon and Cedella. Son Damian has won three Grammys.
