Wotsits packaging often come with a joke or trivia section on the back. The brand was the first to introduce inserts into its packs in 1994, with the insertion of "Pogs". It also inserted merlin football stickers and other inserts aimed at 11-year-old boys. The brand was advertised with the strapline "you only get a whoosh with a Wotsit" between 1994 and 2002 following a campaign designed by JWT of a play on words.
