As of Wednesday, analogue telly is a thing of the past. Well okay, it’s clinging on for a few more months in a couple of parts of the country, but for most of us in the UK old tellies either need to be attached to a digibox or it’s all over. At Ambika P3, David Hall’s End Piece … exhibition (part of which I wrote about here a week or two ago) is a fitting way to mark its passing. The centrepiece of the exhibition is the extraordinary, descriptively titled installation 1001 TV Sets (End Piece). With the analogue switchoff on Wednesday the work went from being a bewildering jumble of images with a cacophonous soundtrack to 1001 different types of snow. The sound is still loud but it’s a constant static now rather than the chaos of five competing television channels.
