Off-the-air
In the broadcasting industry, a dark television station or silent radio station is one that has gone off the air for an indefinite period of time. Usually unlike dead air (broadcasting only silence), a station that is dark or silent does not even transmit a carrier signal. U.S. law Transmitter operations According to the U.S. Federal Communications Commission (FCC), a radio or television station is considered to have gone dark or silent if it is to be off the air for thirty days or longer. Prior to the Telecommunications Act of 1996, a "dark" station was required to surrender its broadcast license to the FCC, leaving it vulnerable to another party applying for it while its current owner was making efforts to get it back on the air. Following the 1996 landmark legislation, a licensee is no longer required to surrender the license while dark. Instead, the licensee may apply for a "Notification of Suspension of Operations/Request for Silent STA" (FCC Form 0386), stating the reas ...

Dead Air
Dead air is an unintended period of silence that interrupts a broadcast during which no audio or video program material is transmitted. Radio and television Dead air occurs in radio broadcasting when no audio program is transmitted for an extended period of time, usually more than a few seconds. In television broadcasting, the term denotes the absence of both audio and video program material. However, a carrier wave is still transmitting. In radio, the result is silence, and in television, the result is a silent black or gray screen. Television directors may use the command "fade to black" or "to black" to indicate a momentary transition to a completely black image. However, the term "dead air" is most often used in cases where program material comes to an unexpected halt, either through operator error or technical malfunction. Among professional broadcasters, dead air is considered one of the worst things that can occur. Moreover, dead air may impact advertising revenue if it a ...

Broadcasting
Broadcasting is the distribution (business), distribution of sound, audio or video content to a dispersed audience via any electronic medium (communication), mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Temporary Authority
Special Temporary Authority (STA) in U.S. broadcast law is a type of broadcast license which temporarily allows a broadcast station to operate outside of its normal technical or legal parameters. In the Federal Communications Commission (FCC) station database (CDBS), broadcast STA applications have a prefix of BSTA (general), BLSTA (legal), BESTA (engineering), or BLESTA (both). STAs can also be issued for other telecommunication services under FCC regulation. Often an STA is necessary due to an unforeseen event. A station operator must exhibit why the STA is necessary and serves the public good. A common reason to apply for STA is an equipment failure. In case a station cannot use its licensed antenna or transmission system, it can immediately continue operations using any available antenna or operating parts of existing system, as long as an STA is filed for within 24 hours. An AM station may use a random wire antenna if necessary. AM stations operating directionally are limited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deregulation
Deregulation is the process of removing or reducing state regulations, typically in the economic sphere. It is the repeal of governmental regulation of the economy. It became common in advanced industrial economies in the 1970s and 1980s, as a result of new trends in economic thinking about the inefficiencies of government regulation, and the risk that regulatory agencies would be controlled by the regulated industry to its benefit, and thereby hurt consumers and the wider economy. Economic regulations were promoted during the Gilded Age, in which progressive reforms were claimed as necessary to limit externalities like corporate abuse, unsafe child labor, monopolization, pollution, and to mitigate boom and bust cycles. Around the late 1970s, such reforms were deemed burdensome on economic growth and many politicians espousing neoliberalism started promoting deregulation. The stated rationale for deregulation is often that fewer and simpler regulations will lead to raised level ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accountability
Accountability, in terms of ethics and governance, is equated with answerability, blameworthiness, liability, and the expectation of account-giving. As in an aspect of governance, it has been central to discussions related to problems in the public sector, nonprofit and private (corporate) and individual contexts. In leadership roles, accountability is the acknowledgment and assumption of responsibility for actions, products, decisions, and policies including the administration, governance, and implementation within the scope of the role or employment position and encompassing the obligation to report, explain and be answerable for resulting consequences. In governance, accountability has expanded beyond the basic definition of "being called to account for one's actions". It is frequently described as an account giving relationship between individuals, e.g. "A is accountable to B when A is obliged to inform B about A's (past or future) actions and decisions, to justify them, and t ...

Lightning
Lightning is a naturally occurring electrostatic discharge during which two electric charge, electrically charged regions, both in the atmosphere or with one on the land, ground, temporarily neutralize themselves, causing the instantaneous release of an average of one Joule, gigajoule of energy. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. The three main kinds of lightning are distinguished by where they occur: either inside a single Cumulonimbus cloud, thundercloud (intra-cloud), between two clouds (cloud-to-cl ...

Mobile Telephone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Television
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widel ...

Great Recession
The Great Recession was a period of marked general decline, i.e. a recession, observed in national economies globally that occurred from late 2007 into 2009. The scale and timing of the recession varied from country to country (see map). At the time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression. One result was a serious disruption of normal international relations. The causes of the Great Recession include a combination of vulnerabilities that developed in the financial system, along with a series of triggering events that began with the bursting of the United States housing bubble in 2005–2012. When housing prices fell and homeowners began to abandon their mortgages, the value of mortgage-backed securities held by investment banks declined in 2007–2008, causing several to collapse or be bailed out in September 2008. This 2007–2008 phase was called the subprime mortgage crisis. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equity Media Holdings
Equity Media Holdings Corporation was a broadcasting company based in Little Rock, Arkansas that owned and operated television stations across the United States. Prior to March 30, 2007, the company was known as Equity Broadcasting, a name later used for its broadcast station subsidiary. The company had a focus on Hispanic and Asian American communities in large markets while owning a combination of English-language network affiliates in medium and small markets. Equity was known for its use of broadcast automation to control dozens of small, local UHF television broadcasting stations from one central Little Rock location; the feeds were readily visible on free-to-air satellite television through much of North America, despite the very small terrestrial footprint of the individual stations over the air. Most commonly, Equity stations were low-power television affiliates of Univision, Fox, The WB/UPN or carried music videos and classic television reruns. In late 2005, Equity laun ...
