With the end of the war in 1945, the company went back into full production and reintroduced a motorized fleet. In 1950, the firm launched Tango, an enduring brand that is still in production. In 1958, the company was bought by the Beecham Group who kept the Corona brand. Although production continued to be centralised in South Wales, depots began to appear all over the United Kingdom. Under new management Corona reached a new audience and during the 1960s was promoted by a series of television advertisements starring British singer and comedian Dave King. With the rise of supermarkets in the late 1960s and 1970s, the public's shopping habits changed and the door-to-door sales reduced. During the 1970s, one of Corona's most memorable advertising campaigns used the slogan Every bubble's passed its FIZZical! In 1987 the company again changed hands, coming under the ownership of Britvic. Britvic closed the Welsh Hills plant in Porth in 1987, with production being transferred to Bolton in Lancashire, England.
