BBC TV interviewed a London University professor who had perfected a technology he called "smellovision," allowing viewers to smell aromas produced in the television studio in their 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 by noon whether they had smelled anything. Numerous viewers called in from across the country to confirm that they had distinctly experienced these scents. Some claimed the onions made their eyes water.
