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

• America One (a successor to Channel America)
• American Broadcasting Company (ABC) (formerly NBC Blue)
• National Broadcasting Company (NBC) (formerly NBC Red)
• CBS (originally Columbia Broadcasting System)
• Fox Broadcasting Company (Fox)
• Omni Broadcasting Network (OBN)
• PAX Network (PAX)
• The WB Television Network (WB)
• Urban America Television (UATV) (a successor to the American Independent Network, AIN)
• UPN (originally Paramount Television Service and United Paramount Network)

...additionally, several of the cable-oriented 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 PAX 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.

• Although ABC, NBC, and CBS were founded prior to 1946, they did not begin continuous over the air TV broadcasting until that year.

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)
