During 2007 Richmond will invest £2 million in advertising campaigns for the Skinny Cow portfolio, with ads for the new smoothies reaching TV screens in February. Press ads will also be used to support the launch.
Brand manager Nicola Hubbs said: "Consumers are looking for healthier products with increased fruit content. We are extending our branded sticks range into luxury fruit refreshment as our research has shown that 76 per cent of consumers want to buy these types of products.
"Retailers have a great opportunity to boost sales by capitalising on this demand."
