Today, more than fifty national free-to-air networks exist. Other than the non-commercial educational (NCE) PBS, which is composed of member stations, the largest terrestrial television networks are the traditional Big Three television networks (ABC, CBS and NBC). Many other large networks exist, however, notably Fox and The CW which air original programming for two hours each night instead of three like the original "Big Three" do, as well as syndication services like MyNetworkTV and Ion Television which feature reruns of recent popular shows with little to no original programming. Fox has just about the same household reach percentage as the Big Three, and is therefore often considered a peer to ABC, NBC, and CBS since it has also achieved equal or better ratings since the late 1990s; as of 2019, it also programs the equivalent amount of sports programming as the Big Three. Most media outlets now include Fox in what they refer to as the "Big Four" TV networks.
Religious broadcast networks – which air religious study and other faith-based programs, and in some cases, family-oriented secular programs (for example, Daystar).
Each network sends its signal to many local affiliatetelevision stations across the country. These local stations then air the "network feed," with programs broadcast by each network being viewed by up to tens of millions of households across the country. In the case of the largest networks, the signal is sent to over 200 stations. In the case of the smallest networks, the signal may be sent to just a dozen or fewer stations.
As of the 2016–17 television season, there are an estimated 118.4 million households in the U.S. with at least one TV set.
CBS (originally the Columbia Broadcasting System) – The nation's second-largest commercial network, it originated as the CBS Radio Network in 1927; the CBS-TV network commenced broadcasts in 1941. Owned now by ViacomCBS, CBS airs original programming, sports and news seven days a week. The network has over 200 owned-and-operated and affiliate stations, almost all of which air local newscasts. For most of its existence, CBS has been the nation's most watched network.
National Broadcasting Company (NBC) – The nation's largest and oldest commercial network, the NBC-TV network was formed out of the NBC Red Network radio service, which launched in 1926; the network commenced television broadcasts in 1939. Owned by NBCUniversal, NBC airs original programming, sports and news seven days a week. It has over 200 owned-and-operated and affiliate stations, almost all of which air local newscasts.
Fox Broadcasting Company (Fox) – The nation's fourth-largest commercial network owned by Fox Corporation, Fox was launched in October 1986 through former parent News Corporation's purchase of Metromedia earlier that year (two of the network's owned-and-operated stations once owned by that group at its founding had formed the hub of the old DuMont Television Network, which existed from 1944 to 1956) and the purchase of the 20th Century Fox film studio, originally established in 1915 as Fox Film Corporation by William Fox and 20th Century Pictures founded 1933 and merged into Fox Film in 1935, five years after founder Fox lost control. After a half-century of up and down success, the studio now by Fox Corporation with Australian and later British and American newspaper chain mogul Rupert Murdoch who had bought into the studio in 1985. Fox airs first-run programming and sports seven days a week, programming two hours each night in primetime (three hours on Sundays), along with political talk program Fox News Sunday on Sunday mornings and the optional infomercial block Weekend Marketplace on Saturday mornings.

It maintains approximately 100 owned-and-operated and affiliate stations in the top 100 television markets; it also has approximately 90 additional cable-only and digital subchannel affiliations in smaller TV markets through a fully programmed feed known as The CW Plus. The network airs two hours of first-run programming in primetime and one hour in daytime on Monday through Fridays, as well as a five-hour children's program block on Saturday mornings called One Magnificent Morning.

W. Scripps Company, Nexstar Media Group and Weigel Broadcasting; despite joint ownership by CBS and WarnerMedia, CBS Corporation serves as the network's de facto O&O station group (Time Warner owned one station in Atlanta through its Turner Broadcasting System subsidiary before it sold the station, however it did not serve as the CW affiliate for the market). Some CW affiliates air local newscasts, most of which are produced by another station in the market though ten of its affiliates (most of which are owned by Tribune Broadcasting) produce local newscasts in-house.
MyNetworkTV – MyNetworkTV is a programming service owned by Fox Corporation, which is also parent of the Fox network. It was hastily formed in February 2006 to provide programming for stations left out of affiliation with The CW, after CBS Corporation and Time Warner chose to shut down The WB and UPN to form that network. The network launched in September 2006 with a format of English-language telenovelas, but gradually switched to mainly low-budget programming by the end of its first year. Since it converted from a TV network into a programming service in 2009, MyNetworkTV fills its two-hour primetime schedule on Monday through Fridays with reruns of drama series that originated on other broadcast and cable networks. Some MyNetworkTV affiliates air local newscasts, most of which are produced by another station in the market (San Francisco affiliate KRON-TV is the only affiliate that produces its local news programming in-house). Some affiliates also carry the nightly scheduled out of primetime to accommodate those newscasts and alternate programming (or in the case of several affiliates are primary Fox affiliates), and offer MyNetworkTV as a late night offering instead.
Ion Television – Ion (originally known as Pax TV from 1998 to 2005, and i: Independent Television from 2005 to 2007) is a mid-sized network owned by Ion Media Networks; it airs off-network repeats of recent television series and select English-language imported programming, as well as feature films for eighteen hours per day.

Nomenclatures for commercial networks
Nicknames referring to the major American networks (most established by the industry publication Variety as "slanguage") are as follows:
ABC: "Alphabet network" (its name is also the first three letters of the alphabet) or "circle network" (the network's logo, used since 1962, is a circle with its initials in lower-case)
CBS: "Tiffany network" or "eye network" (for the network's high-toned reputation and eye logo, respectively)
Fox Broadcasting Company: referred to by media outlets and by the network itself by the capitalized "FOX", and the legal name is only used in industry media and legal documents
PBS: "Head Network" (in reference to the network's educational programming, mascot, and logo)
UPN(defunct): "Used Parts Network" (for its acquisitions of series formerly seen on other networks to broadcast new episodes), "Shapes network" or "Disc network" (after the network's 1995 to 2002 and 2002 to 2006 logos)
The WB(defunct): "Frog network" or, the network's secondary branding, "The Frog" (after the network's mascot, Warner Bros. animated character Michigan J. Frog)

Spanish-language commercial networks

Some Mexican border stations (such as the former English-language ABC/Fox/CW affiliate XETV-TDT in Tijuana) who formerly maintained affiliations with U.S.-based English or Spanish networks, but mainly targeted their programming at their American border city (more than the Mexican metropolitan area that they are based in or merely licensed to).
Although the English-language programming model in the U.S. traditionally relies on the network and its stations handling programming responsibilities, Spanish language networks handle most of the responsibility for programming, while affiliates are limited to breakaways from the network feed to provide local news, public affairs and/or entertainment programming as well as local advertising.
