St Ivel has teamed up with popular kids' brand Bang on the Door to introduce a new range of Groovy Chick products including four-packs of yogurt and drinking yogurt. It hopes the tie-up will grow St Ivel's self-proclaimed 35% share of the growing £33m kids' licensing market. The dairy produce giant's licensed pre-school range currently includes Tweenies and Teletubbies yogurts and Bill & Ben fromage frais. But it hopes the new addition will help it crack a bigger share of tweens' consumers. Rsps for the new additions, which go into stores from June 17, will be £1.19 for the 4x90g yogurts and £1.29 for the 4x100ml drinks. The launches will be supported by a promotion on kids satellite TV channel Nickelodeon set to run for seven weeks over the summer holidays. Web site and instore activity is also planned. {{P&P }}
