Wotsits

Wotsits is a British brand of cheesy flavour corn puffs sold first by Golden Wonder and later by Walkers Crisps. The most common form is "Really Cheesy flavour corn puffs". Other shapes and flavours have also been sold, including limited-edition varieties.The brand name occurs in the singular, "Wotsit", referring to an individual corn puff. It is an allusion to the slang term "whatsit", to which it is phonetically identical.
In December 2002, Golden Wonder changed hands and sold the Wotsits product range to Walkers in January 2003. Prior to this, Walkers sold the similar American product Cheetos, which was considered a rival in the UK market. Walkers relaunched Cheetos in the UK in June 2015 and both brands are sold together.

Advertising.
In 2003, the advertising agency Abbott Mead Vickers made a public apology when the Parliamentary Select Committee on Health brought to light a private brief that it had made to Frito-Lay (Walkers' owners) where it proposed encouraging children (4 to 9 years old) to believe that "Wotsits are for me—I'm going to buy them when I get the chance and pester Mum for them when she next goes shopping".
