Entertainments National Service Association

The Entertainments National Service Association (ENSA) was an organisation established in 1939 by Basil Dean and Leslie Henson to provide entertainment for British armed forces personnel during World War II. ENSA operated as part of the Navy, Army and Air Force Institutes. In 1946 it was re-named to Combined Services Entertainment (CSE) operating under the Services Sound and Vision Corporation (SSVC), until 2 March 2020, when the SSVC re-branded to the British Forces Broadcasting Service (BFBS), with the CSE likewise re-branding as BFBS Live Events.
