Big Breadwinner Hog is a British television thriller serial devised by Robin Chapman, produced by Granada TV and transmitted in eight parts, starting at 9.00pm on 11 April 1969 on the ITV network. It portrayed the ruthless rise through the criminal underworld of the trendy young London gangster Hogarth. He exploits the resources of a declining gangster, Ryan, to take over the dominant crime syndicate Scot-Yanks, controlled by the equally ruthless and manipulative Lennox. The key to Hogarth's success is knowledge of a murder arranged by Lennox, of which there is a crucial witness, Ackerman, a one-time private eye who has been blackmailed into working for Scot-Yanks, and bitterly resents Lennox as a consequence.
