So often in life and in news, let's be frank, the urgent drives out the important. And when it comes to important, there is nothing more important than the question of the threat of nuclear weapons worldwide. The Nuclear Threat Initiative just issued its most recent biennial report and it's a mixed bag. On one end, worldwide efforts to secure and eliminate deadly nuclear materials have made real progress - reducing the number of countries with dangerous materials from 32 to
List of United States cable and satellite television channels In the United States, television is available via broadcast also known as "over-the-air" or OTA — the earliest method of receiving television programming, which merely requires an antenna and an equipped internal or external tuner capable of picking up channels that transmit on the two principal broadcast bands, very high frequency VHF and ultra high frequency UHFin order to receive the signal — and four conventional types of multichannel subscription television: There are also competing video services on the World Wide Webwhich have become an increasingly popular mode of television viewing since the late s, particularly with younger audiences as an alternative or a supplement to the aforementioned traditional forms of viewing television content; the s saw the development of several virtual MVPD services offering "skinny" tiers of channels originally developed for cable and satellite distribution at a reduced base price compared to providers utilizing the more established pay television distribution methods.
Individual broadcast television stations in the U. During the era of analog televisionbroadcast stations transmitted on a single universal channel; however due to the technical complexities of the present digital television standard, most stations now transmit physically on an RF channel or "minor channel" that is mapped to a virtual channel or "major channel"which — with some exceptions — typically differs from their physical allocation and corresponds to the station's former analog channel.
The UHF band originally spanned from channels 14 to 83, though the Federal Communications Commission FCC has twice rescinded the high-end portions of the band from television broadcasting use for emergency and other telecommunications purposes in when channels 70 to 83 were removed and when channels 52 to 69 were removed by mandate at the completion of the transition from analog to digital television.
As in other countries, television stations require a license to broadcast legally which any prospective broadcaster can apply for through the FCC and must comply with certain requirements such as those involving programming of public affairs and educational interest, and regulations prohibiting the airing of indecent content in order to retain it; the FCC's Board of Commissioners maintains oversight of the renewal of existing station licenses approaching their expiration, with individuals or groups who wish to oppose the granting of a renewal to a licensee based on any disagreement over rule compliance or any other issues inclined to contest it for consideration of revocation.
Free-to-air and subscription television networks, however, are not required to file for a license to operate. Over-the-air and free-to-air television do not necessitate any monthly payments, while cable, direct broadcast satellite DBSIPTV and virtual MVPD services require monthly payments that vary depending on the number of channels that a subscriber chooses to pay for in a particular package.
Channels are usually sold in groups known as "tiers"rather than singularly or on an a la carte basis. Most conventional subscription television services offer a limited basic or "lifeline" tier, a minimum base package that includes only broadcast stations within the television market where the service is located, and public, educational, and government access PEG cable channels; in many smaller markets, this tier may offer stations from adjacent markets that act as default network affiliates for areas not served by a local affiliate of one or more of the major broadcast networks; however, since the digital television transition in the late s, these have been replaced in some cases by digital subchannels that have agreed to provide a particular network's programming within the local market.
Elevated programming tiers commonly start with an expanded basic package, offering a selection of subscription channels intended for wide distribution primarily those that launched between the s and the s ; since the upspring of digital cable and satellite television during the mid- and late s, additional channels with more limited distribution are offered as add-ons to the basic packages through separate tiers, which are commonly organized based on the programming format of the channels sold in the tier.
A la carte subscription services in the U. Terrestrial television and List of United States over-the-air television networks The United States has a "decentralized", market-oriented television system, particularly in regard to broadcast television.
Local media markets have their own television stations, which may either be affiliated with or owned and operated by a television network. Stations may sign affiliation agreements with one of the national networks for the local rights to carry their programming; these contracts can last anywhere from one to ten years, although such agreements often last on average between four and six years.
Except in very small markets with a limited number of commercial stations generally, fewer than fiveaffiliation agreements are usually exclusive: Arrangements in which television stations carried more than one network on its main signal which often resulted in some network programs being not being cleared to air locally by the station, thereby limiting their national carriage and resulting in viewers having to rely on an out-of-market station receivable in their area that airs the locally pre-empted show through an affiliation with that same network in order to see it were more common between the s and the s, although some arrangements continued as late as However unlike in other countries, to ensure local presences in television broadcasting, federal law restricts the amount of network programming that local stations can run.
Until the s and s, local stations supplemented network programming with a sizeable amount of their own locally produced shows, which encompassed a broad content spectrum that included varietytalkmusic and sports programming.
The international programming model is used in the U. The federal government has imposed limits on how many stations an individual owner can hold. The earliest limits restricted owners from holding more than five stations across the entire country, and no more than one in any given market.
As ofthese limits have been relaxed substantially. The "discount" was repealed by the FCC under Chair Tom Wheeler and his Democrat -led board inbut was reinstated by Wheeler's successor and former board colleague, Ajit Pai and his fellow Republican commissioners in April The largest ownership group in terms of coverage of the U.
Two other ownership groups in particular, Sinclair Broadcast Group and Nexstar Media Groupdo not produce network programming Sinclair has produced original programs for its stations but not on a full-time network including the four multicast services it distributes to its own stations and those owned by partner companies and other unaffiliated group owners but each own over stations, each covering over three-eighths of the country.

The first and elder three which are colloquially known as the " Big Three " began as radio networks: Fox is a relative newcomer that began operation on October 6, with a limited schedule of late-night programming the network would launch a weekend-only prime time lineup seven months later on April 9,although it is built upon the remnants of the former DuMont Television Networkan earlier attempt at a " fourth network " that operated from January to August ; the Paramount Television Network also flourished simultaneously, if less successfully.
