List of United States over-the-air television networks

In the United States, for most of the history of broadcasting, there were only four major national broadcasting networks. From 1946-1956 these were ABC, CBS, NBC, and the DuMont Television Network. After that and until 1969, the national networks were ABC, CBS, NBC, and NET. After 1969 and until 1986, the four main national networks were ABC, CBS, NBC, and PBS.

Today, more than 20 nation-wide broadcasting networks exist, although some of these are admittedly quite small. Other than PBS, which has the largest number of member stations, the largest broadcast networks remain the traditional Big Three Television Networks (ABC, CBS, and NBC). Many other large networks exist, however, notably Fox, UPN, and The WB.

Broadcast networks in the United States can be divided into four categories:

• Commercial broadcasting networks (which air English-language programming to a general audience).

• Educational (non-commercial) broadcasting networks (which air English-language programming to an audience for the purpose of learning).

• Religious broadcasting networks.

• Spanish-language broadcasting networks.

Each network sends its signal to many local TV stations across the country. These local stations then air the "network feed," and 103,000,000 viewers across the country tune in. In the case of the largest networks, the signal is sent to over 200 TV stations. In the case of the smallest networks, the signal may be sent to just a dozen or fewer stations.

Analog over-the-air television channels are numbered 2 through 69, and occupy the following frequencies:

• 54–88 MHz (Channels 2-6) VHF
• 174–216 MHz (Channels 7-13) VHF
• 470–806 MHz (Channels 14-69) UHF

English-language American commercial over-the-air television networks

• America One (a successor to Channel America) A small network comprised of 76 local stations, A1 airs many old films and a few original shows.
• American Broadcasting Company (ABC) (formerly NBC Blue) The nation's third-largest commercial network, ABC has over 200 affiliate stations and airs original programming seven days a week.
• NBC (originally National Broadcasting Company) (formerly NBC Red) The nation's largest commercial network, NBC has over 200 affiliate stations and airs original programming seven days a week.
• CBS (originally Columbia Broadcasting System) The nation's second-largest commercial network, CBS has over 200 affiliate stations and airs original programming seven days a week. CBS's audience is composed primarily of older viewers.
• Fox Broadcasting Company (FOX) The nation's fourth-largest commercial network, Fox has nearly 200 affiliate stations and airs original programming seven days a week. Fox broadcasts to a younger audience than the "Big Three". Some FOX stations broadcast news (usually a 10pm/9pm news, others air AM news)
• Omni Broadcasting Network (OBN) A very small network composed of low-power TV stations in around 20 areas.
• i A mid-sized network which airs original family-oriented programming a few days a week. i's affiliates number roughly around 100.
• The WB Television Network (WB) A mid-sized network, the WB airs original programming most of the week. It has around 150 affiliate stations, and broadcasts to a mainly teenaged audience. Some WB Stations broadcast news.
• Urban America Television (UATV) (a successor to the American Independent Network, AIN) A small network with 60 affiliate stations, UAT airs original programming mixed with old films.
• UPN (originally Paramount Television Service and United Paramount Network) A mid-sized network, UPN broadcasts to a younger audience. The network has over 150 affiliate stations. Some UPN stations air news
• TVS Television Network. An occasional over the air network, TVS specializes in sports and entertainment programming since 1961. Average affiliates for a TVS telecast are 100-120 stations, both independent and network affiliates.

...additionally, several of the cable-oriented theme channels (e.g. music or shopping channels) have obtained broadcast clearances, usually on low-power stations, in many markets. Among these are Home Shopping Network or HSN, and ShopNBC.

The WB, UPN and i are sometimes called "netlets" because they do not currently have the affiliate reach of the larger networks. UATV and America-1 are even smaller networks, many of whose affiliates take their program offers out of pattern, which is to say they schedule them at their own convenience. Several of the religious broadcasting networks also have out-of-pattern clearance arrangement with their broadcast affiliates, notably FamilyNet, Trinity Broadcasting Network, and World Harvest Television. And, of course, the Public Broadcasting Service also allows its member stations to run their programs out of pattern.

Nicknames of major American networks are as follows:

• ABC: "Alphabet network"
• NBC: "Peacock network" (after the network's peacock logo)
• CBS: "Tiffany network" or "Eye network" (for the network's high-toned reputation and eye logo, respectively)
• WB: "Frog network" (after network mascot Michigan J. Frog)
