Cable antennas were erected on mountains or other high points and homes connected to the towers. Much attention was focused on increasing the picture resolution (high-definition television [HDTV]) and on changing the dimensions of the television receiver to show wide-screen pictures. First available in 1998, HDTV products were initially extremely expensive, priced between $5,000 and $10,000 per set. The number of programs that these early stations aired was often limited, in part due to the expense of program creation. Most people thought the concept was lunacy.

Displaying a widescreen aspect (rectangular) image on a conventional aspect (square or 4:3) display can be shown: A conventional aspect (square or 4:3) image on a widescreen aspect (rectangular with longer horizon) display can be shown: A common compromise is to shoot or create material at an aspect ratio of 14:9, and to lose some image at each side for 4:3 presentation, and some image at top and bottom for 16:9 presentation. The technical standards for modern television, both monochrome (black-and-white) and colour, were first established in the middle of the 20th century.

Television signals may be delivered by using antennas broadcast communication satellites or cable systems. David Byrne, Stephanie Hsu and Son Lux to Perform at Oscars 2023. Higher bandwidth makes receiver design more complicated, requires higher radio frequencies to be used, and may limit the number of channels that can be allocated in a given area; the same radio frequencies useful for television are also in high demand for other services such as aviation, land mobile radio, and mobile telephones. Similarly, while the frame rate of sound films is 24 per second, the screen scanning rate of the NTSC is 29.97 Hz (per second), which requires a complex scanning schedule. Analog TV has a fascinating history from when broadcasts were first started (in Black and White), through to the adoption of color TV (using a totally backwards-compatible system with the earlier monochrome standard), through to cable, and now digital.

The largest television network in the United States, however, is the Public Broadcasting Service (PBS), a non-profit, publicly owned, non-commercial educational service. A joint international collaboration between ATT Bell Labs NASA British General Post Office the French National Post Telegraph and Telecom Office results in the development and launch of Telstar the first satellite to carry TV broadcasts. It would continue in this way, transmitting information on how much light was seen at each portion, until the entire picture was scanned, in a manner similar to the eye reading a page of text. This is measured in candela per square metre (cd/m2). Television is now delivered in a variety of ways: over the air by terrestrial radio waves (traditional broadcast TV); along coaxial cables (cable TV); reflected off of satellites held in geostationary Earth orbit (direct broadcast satellite, or DBS, TV); streamed through the Internet; and recorded optically on digital video discs (DVDs) and Blu-ray discs. In 2021, the average viewing time of TV was 3 hours and 17 minutes, where it is estimated to backslide to about 2 hours and 51 minutes in 2023.

The first non-terrestrial method of delivering television signals that in no way depended on a signal originating from a traditional terrestrial source began with the use of communications satellites during the 1960s and 1970s.

Licenses for these experimental stations were often granted to experienced radio broadcasters, and thus advances in television technology closely followed breakthroughs in radio technology.
