 In the 1980s, CAMRA was influential in campaigning against the "Big Six" breweries who had a stranglehold on the UK's pubs.This resulted in The Supply of Beer (Tied Estate) Order 1989, more commonly known as the Beer Orders.The orders limited the number of pubs that a brewery could own but an unintended consequence was that many breweries ceased producing beer to focus solely on being pub-owning businesses or PubCos.
