Color television made a large impact on American society, in that it changed the way and the amount of time people watched their favorite television shows and purchased new color TV's. In the beginning only the well to do or people with money could afford to have a color television, so it was a bit of a status symbol to have a color set. When color TV's were first introduced to the American house hold a lot of the TV's shows were not in color, but that rapidly changed with more and more households getting the color sets. It is quite similar to the effect of digital and high definition flat screen TV's, versus the old color analog sets, and how that has once again changed how people relate to television.
