Notwithstanding this distinction, it is common in informal speech (even for networks or O&Os themselves) to refer to any station, O&O or otherwise, that carries a particular network's programming as an affiliate, or to refer to the status of carrying such programming in a given market as an "affiliation".
Overview
Stations which carry a network's programming by method of affiliation maintain a
contractual agreement
A contract is a legally enforceable agreement between two or more parties that creates, defines, and governs mutual rights and obligations between them. A contract typically involves the transfer of goods, services, money, or a promise to tran ...

revenue to the network). Affiliation contracts normally last between three and five years, though contracts have run for as little as one year or as long as ten; in addition, if a company owns two or more stations affiliated with the same network, affiliation contracts may have end-of-term dates that are the same or differ among that company's affiliates, depending on when a particular station's affiliation agreement was either previously renewed or originally signed.
While many television and radio stations maintain affiliations with the same network for decades, on occasion, there are certain factors that may lead a network to move its programming to another station (such as the owner of a network purchasing a station other than that which the network is already affiliated with, the network choosing to affiliate with another local station in order to improve local viewership of its programming by aligning with a stronger station, or a dispute between a network and station owner while negotiating a contract renewal for a particular station such as those over reverse compensation shares), often at the end of one network's existing contract with a station. One of the most notable and expansive affiliation changes occurred in the

While network-owned stations will normally carry the full
programming schedule of the originating network (save for major local events), an affiliate is independently owned and typically under no obligation to do so. This is especially the case for network shows airing outside the network's primetime hours. Affiliated stations often buy supplementary programming from another source, such as a
broadcast syndication service, or another television network which otherwise does not have coverage in the station's broadcast area. Some affiliates may air such programs instead of those from their primary network affiliation; a common example of this was the popular syndicated

ultimately allowed control over the network as a whole, turning former member stations into CTV O&Os.
Dual affiliations
In some smaller markets in the United States, a station may even be simultaneously listed as an affiliate of two (or in rare cases, three) networks. A station which has a dual affiliation is typically expected to air all or most of both networks' core day time and/or prime time schedules – although programming from a station's secondary affiliation normally airs outside its usual network time slot, and some less popular programs may simply be left off of a station's schedule; this form of dual affiliation was the norm before the digital age. Dual affiliations are most commonly associated with the smaller American television networks, such as The CW and MyNetworkTV, which air fewer hours of prime time programming than the "Big Four" networks and can therefore be more easily combined into a single schedule, although historically the "Big Four" have had some dual-affiliate stations in small markets as well and in some cases, affiliates of more than two networks (including a few that had affiliations with ABC, NBC, CBS and
DuMont during the late 1940s through the mid-1950s, when fewer television stations existed in a particular market, especially those that would eventually be able to support four commercial outlets).
Historically, the sole commercial station in a market would commonly take affiliations or secondary affiliations from most or all of the major national networks. As a local monopoly, a station could become a primary affiliate of one of the stronger networks, carrying most of that network's programming while remaining free to "cherry-pick" popular programming from any or all of the rival networks. Similarly, some markets that had two commercial stations shared a secondary affiliation with one network, while maintaining separate primary affiliations (such as in the

systems) has significantly reduced the number of one-station markets (limiting them to those with population densities too small to be able to make any additional stations economically viable), providing networks with a larger selection of stations as potential primary affiliates. A new station which could clear one network's entire programming lineup better serves the network's interests than the former pattern of partial access afforded by mixing various secondary affiliations on the schedule of a single local analog channel.
