BBC TV interviewed a London University professor who had perfected a technology called Smellovision that allowed the transmission of smells over the airwaves. Viewers would be able to smell aromas produced in the television studio in their own homes. The professor explained that his machine broke scents down into their component molecules which were then transmitted through the screen. The professor demonstrated by placing some coffee beans and onions into the smellovision machine. He asked viewers to report whether they had smelled anything. Numerous viewers called in from across the country to confirm that they had distinctly experienced these scents. Some even claimed the onions made their eyes water.
