Wrigley has teamed up with the youth-oriented MTV channel for a promotion across all four flavours of Extra chewing gum. Starting next month, 130 million Extra packs will carry an MTV logo outside and a number inside. Consumers can use the numbers to win prizes through MTV's website. The music station will run ads for three months. Prizes up for grabs include flight, accommodation and concert ticket packages to European destinations, and compilation CDs. Jo Hartop, Wrigley's communications manager, said the campaign provided a "powerful link" with Extra's target audience of 16 to 35-year-olds. {{P&P }}
