The difference in analog and digital is pretty simple. If you live in the United States and use a regular antenna to get television signals over the air, this is probably the reason why you can't see your old stations today.

To receive digital television signals, some people need a converter box. The idea was to make sure few people are left behind, but their efforts caused some confusion. The original date for the analog-to-digital transition had to be moved because the FCC needed to raise awareness of the change among the population. The remaining portion of the broadcast signal will be available to consumers for wireless services. One reason for the switch was to free up space for police, fire and other public safety communications. The reason? Broadcasters moved their signals to another part of the radio spectrum. Regular broadcasters in the United States have completed the transition to digital television (DTV). 17, 2009, some analog channels in the United States went dark - with a few exceptions, the rest did so on June 12.

If you live in an area near a broadcast station, you can still plug a pair of rabbit ears into the antenna jack on the back of your set and get programming. But in general, you don't have to have all those things to watch TV.

Unfortunately, his color-broadcasting standard wasn't compatible with existing TV sets, and in 1953, the National Television Standards Committee (NTSC) adopted RCA's method of color broadcasting instead.įrom there, we have incremental introductions - the remote control, cable and satellite providers, and videocassette recorders ( VCRs), et cetera. Ĭolor TV was around as early as 1946, when CBS engineer Peter Goldmark - who also had a hand in creating the long-playing vinyl record - developed a method of broadcasting in color. And by 1960, there were 515 commercial stations, with TVs in 85 percent of American homes. In 1945, there were only nine commercial TV stations broadcasting, but by 1949, there were 48. Though there were regular broadcasts, people at large didn't adopt television until after World War II. Early television began in the 1870s, but TV didn't really catch on until the introduction of electronic television in the early 20th century. As important as television is to many people in the United States, the technology behind the medium hasn't changed that much since its introduction.
