The first color television broadcast was an hour-long program broadcast on CBS on June 25, 1951. However, since most television sets were unable to broadcast in color, only a few people were able to view the event, mostly in CBS television studios. Color broadcasting was halted for a time by the Korean War, and the first coast-to-coast color broadcast was the Tournament of Roses Parade on January 1, 1954.

The first full smell-o-vision broadcast was a two hour Thanksgiving cooking extravaganza on The Food Network on November 22, 2211. The event enhanced chef Emeril Lagasse VIII’s television cooking show empire, and left home audiences literally drooling. The first full-smell movie, The Next War of the Roses, is slated to hit theaters in June 2212. But smell-o-vision has more important implications for the future. Like the canary down the well, smell-o-vision broadcasts will allow rescue workers to identify noxious gasses before entering disaster areas. They will also allow schoolchildren on Earth and Jupiter a fuller information exchange on planetary flora without the inconveniences of space travel. Without a doubt, this is the biggest change in broadcasting since the introduction of color 260 years ago.
