The 18th window of the CVTNAC springs open to reveal this floor plan of studio G at Lime Grove, the compact complex occupied by BBC Television from 1950 to 1991. Over the years, G was home to shows like Dee Time and Top of the Pops, but its rectangular shape made it less ideal for situation comedies. The first Hancock's Half Hour TV series was made here, but the various sets had to be placed in a line along one wall, with the audience a few seats deep along the other, with a majority of audience members unable to see what was going on at any given time. It was never converted to colour and closed in the very early 1970s.
