The series is and was noted by many reviewers as a critique of the Margaret Thatcher era, which was seen as being responsible for the fate of many of the unemployed lower and working classes, particularly in the North of England (and in fact fuelling the North-South divide). By early 1982, unemployment had reached 3 million (some one in eight of the workforce) as a result of economic recession and restructuring of industry. Indeed, the most memorable and poignant of the characters was Yosser Hughes, a man driven to the edge of his sanity by the loss of his job, his wife, the authorities' continued attempts to take his children away from him and his constant attempts at salvaging his male pride (often being the main give-away of his insecurity). His catchphrases, "Gizza' job!" ("give us a job") and "I can do that!" became part of the popular consciousness of the Eighties.
Radio City Tower (also known as St. John's Beacon) was built in 1969 and opened by Queen Elizabeth ll. From 1969 - 1999 The top of the tower was a revolving restaurant, the facade and floor of the restaurant revolving as one unit, while the roof of the restaurant was used as an observation platform for visitors. The tower was then refurbished in 1999 at a cost of £5 million. It reopened as Radio City 96.7 (and Magic 1548) in August 2000 and is still used as a radio tower today.
