Britvic and Coca-Cola are vying for teenage taste buds with the launch of summer campaigns for Tango and Fanta. The Tango Ad Game challenges students in the target 16 to 18 year old audience to write their own ads for Tango. Packs have been sent out to schools, taking students through the different stages of advertising. The winner spends the day at Tango's ad agency in London and broadcasts their one minute Tango ad on radio. Also, from May 21, Tango Talk' gives away £1.50 in free mobile phone calles on promotional 500ml bottles of Tango. Fanta's Best Mates Challenge, on 330ml cans and 500ml bottles, gives teenagers the chance to star in the next Fanta ad. {{MARKETING - P&P }}
