Fishsticks first came about as a result of Clarence Birdseye's invention of the plate froster in 1929, the first quick freezer. To ensure rapid freezing, food needed to be in slim rectangular slabs. A suitable candidate for this freezing method was fishsticks, slivers cut from large fish then dipped in bread crumbs for frying. However, it was Gorton's who introduced the snack initially.

In Britain in the 1950's, most of the herring catch was pickled and exported to other North European countries. In an attempt to make herring more appealing on the home market, companies tried to present it in a new way, creating herring fishsticks called 'herring savouries' and were tested on the market against a bland control product of cod sticks, sold as 'fish fingers.' Shoppers in Southampton and South Wales, where the test was conducted, confounded expectations by showing an overwhelming preference for the cod. Cod fishsticks were first produced in Great Yarmouth and introduced in Britain on 26 September 1955. They became immensely popular after television advertising began in 1958.
