For some reason, many technical schools associate the CRT (cathode ray tube) with the receiving tube and consider it obsolete because it is a "tube." Nothing could be further from the truth. In the year 2K, it has been estimated, 300,000,000 CRTs will be built. In addition, the CRT can be adapted to the new 9 by aspect 16 ratio and the new sweep frequencies. Because of its cost compared to the flat screen, the CRT will continue to be in service for many years to come. Few people can afford to spend some $20,000 for a large screen that can be hung on the wall!
