Our initiatives

What’s important to our customers is just as important for us and our business. That’s why we partner with business communities, the governments and NGOs to act on important business issues like littered gum, nutrition labelling regulations and health.

Wrigley through the years

We've come a long way in 100 years: from small beginnings in a single office in London to becoming the UK's biggest seller of chewing gum.


Wrigley sets up in Heppells, a chemist in London's Piccadilly. One of our first major hurdles was to change attitudes about chewing in public in a somewhat austere Edwardian Britain!


During the First World War many soldiers chewed gum in the trenches, and this new habit travelled back with them and coincided with the wide-ranging social changes of the 1920s.


Along with the change in social attitudes post-war came a growing demand for chewing gum, and to help meet it we opened our first factory in Wembley in 1927.


Chewing gum has been recommended by dental professionals for many years, and as long ago as 1950 a paper was presented at the AGM of the BDA recommending chewing gum.


Because of wartime rationing, gum had started to be seen as a glamourous, luxury item. After rationing ended in the 1950s, chewing gum was one of the items people desired.


By the 1970s gum was reaching new heights of popularity and we moved from Wembley to a bigger factory in Plymouth, officially opened by HRH the Duke of Edinburgh in 1972.


Orbit®, the world's first sugarfree chewing gum, is launched, pushing Wrigley into new territory and reaching new, more health-conscious customers.


We've continued to innovate with new brands, which are now part of everyday life for millions. 2003 saw the launch of Extra Mints®, an extension of one of our best-loved brands.


Our centenary year saw the launch of Extra Ice® with microgranules, accredited by the British Dental Health Foundation. We've also set up many projects like the Wrigley Tooth Fairy Fund.


Major launches include our new Fresh Mint and Strawberry Extra® varieties, and we're constantly looking at ways to get our message out to encourage people to chew for better oral health.


2015 saw the introduction of a distinctive new packaging design for EXTRA® and a new improved taste for some of the most popular products in EXTRA the range. The product re-formulations and fresh visual identity aim to drive home the brand’s outstanding oral care credentials to a global audience
