The black and white TV eraBack
Swedish television broadcasts were started by Swedish Radio in Stockholm in 1957. Gothenburg's technical university, Chalmers, had then had trial transmissions for a couple of years. The link from Stockholm to Gothenburg and Malmö was completed in 1958 in connection with the football world Cup. Programme time was gradually increased and sales of television sets increased significantly. It was boom time for TV dealers.
You could also build your own TV. There were kits that could be purchased at electronic retailers. There were also TV-building courses for handy people.
We had black and white TV in one channel for 12 years until 1969 when TV2 started. Since the programs were broadcast on UHF frequencies it was necessary to buy new appliances or a box that transformed the signals from UHF to VHF.
