North Devon is some distance from Britain's traditional areas of industrial activity and population. In the late 1970s it gained several industrial firms due to the availability of central government grants for opening factories and operating them on low or zero levels of local taxation. This was scarcely successful, with few lasting beyond the few years that grants were available. One success was the manufacturing of generic medicines by Cox Pharmaceuticals (now branded Allergan), which moved in 1980 from a site in Brighton, Sussex. A lasting effect on the town has been the development and expansion of industrial estates at Seven Brethren, Whiddon Valley and Pottington.
