Watson Pharmaceuticals Inc

A maker of generic medicines, Watson Pharmaceuticals produced affordable copies of brand-name drugs for patients, pharmacies, and healthcare providers across the US and beyond. Founded in 1983, the company built itself into one of the country's largest generic-drug businesses before merging with Actavis in 2012 and taking on the Actavis name. Watson's origins trace to its founding name, and its growth came from both its own medicines and a series of acquisitions that expanded its reach.
