Princes Foods is investing £2m in a brand building campaign designed to show how versatile canned food can be. The ads have a Best Before ...' theme featuring a variety of humorous situations ­ and showing how Princes products can be healthy and convenient in those situations. Princes said: "Research showed that Princes is seen as a product range rather than a brand in its own right. The message is that canned food isn't boring and can be applied to the way different people live their lives." Breaking this weekend, activity includes press and poster ads, sales promotion and PR. {{P&P }}
