Monster Munch is a baked corn crisps range by Walkers, formerly Smiths. The range was originally known as 'The Prime Monster' when it launched in 1977 but was renamed to its current name in 1978.
When Smiths launched the range in 1977 there were four flavours; Roast Beef, Smokey Bacon, Pickled Onion and Prawn Cocktail. Each had a corresponding monster. There were originally two shape of crisps, the well known 'paw' shape which is still used and one representing one of the monsters. Various other flavours were used during this period; Saucy Tomato, Cheese & Onion and Salt & Vinegar.
In 1995, the Monster Munch brand was taken over by Walkers.
Coinciding with the launch of the new Walkers logo, the packaging design of all the crisp ranges (including Monster Munch) were changed. The packaging of Monster Munch was unusual in that some of the packaging had a horizontal design rather than the traditional vertical. Other than the packaging, nothing else about Monster Munch changed during this period, including the monsters.
In 2008, the Monster Munch range was completely revamped. The redesign was inspired by the original 1977 design, so much so that the packaging is almost exactly the same as it was previously. The size of the crisps have become the same size as they were originally in 1977. The original monsters, except the orange monster which formerly represented Prawn Cocktail, also made a return. The flavours however, remained largely the same as the previous incarnation; Roast Beef, Pickled Onion and Flamin' Hot. Note the slight change to the original logo, it has the word 'Mega' above it to indicate the larger size of the crisps compared to the range launched in 1998.
