Nestlé is injecting dynamism into established children's brand Smarties this year, with a £3m marketing spend, sponsorship of GMTV's Diggit programme, and a cola addition to the brand's stable of limited editions. The red and brown cola Smarties, available from June 5, come in red and white tubes with silver caps. Cola is a favourite flavour among seven year olds ­ the target audience. TV ads for Smarties Tubes, Eggs and Giant Smarties are planned for later in the year. The year long Diggit sponsorship was revamped in April. {{P&P }}
