Dark (broadcasting)
In broadcasting, 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 reason why the ...

Broadcasting
Broadcasting is the data distribution, distribution of sound, audio audiovisual content to dispersed audiences via a electronic medium (communication), mass communications medium, 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, most implementations 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] |
WDHS
WDHS (channel 8) was a television station licensed to Iron Mountain, Michigan, United States, which served the Central and Western Upper Peninsula of Michigan. The station was owned by Withers Broadcasting Companies. WDHS' transmitter was located on East B Street in Iron Mountain. The station was dark for much of its history; it came on the air only for a short period on an annual basis merely as a way to keep its Federal Communications Commission (FCC) license active. The WDHS license was canceled on November 19, 2015, months after an FCC policy change negated the "once per year broadcast" method of retaining a station license which had been exploited in the radio industry to "warehouse" prominent call letters in small markets, along with television broadcasters holding out for sales partners. When WDHS was on the air, it theoretically could serve parts of Baraga, Delta, Dickinson, Gogebic, Houghton, Iron, Marquette and Menominee counties in Michigan, and Florence, Fores ...

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, and 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 raise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accountability
In ethics and governance, accountability is equated with answerability, culpability, 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, private (corporate), and individual contexts. In leadership roles, accountability is the acknowledgment of and assumption of responsibility for actions, products, decisions, and policies such as administration, governance, and implementation, including the obligation to report, justify, 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 to suffer punishment in the case of eventual misconduct."

Lightning
Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions. One or both regions are within the atmosphere, with the second region sometimes occurring on the land, ground. Following the lightning, the regions become partially or wholly electrically neutralized. Lightning involves a near-instantaneous release of energy on a scale averaging between 200 megajoules and 7 gigajoules. The air around the lightning flash rapidly heats to temperatures of about . There is an emission of electromagnetic radiation across a wide range of wavelengths, some visible as a bright flash. Lightning also causes thunder, a sound from the shock wave which develops as heated gases in the vicinity of the discharge experience a sudden increase in pressure. The most common occurrence of a lightning event is known as a thunderstorm, though they can also commonly occur in other types of energetic weather systems, such ...

Mobile Telephone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recording, and gaming. ...

2016 United States Wireless Spectrum Auction
The 2016 United States wireless spectrum auction, officially known as Auction 1001, allocated approximately 100 MHz of the United States Ultra High Frequency (UHF) spectrum formerly allocated to UHF television in the 600 MHz band. The spectrum auction and subsequent reallocations were authorized by Title VI (The Spectrum Act) of the payroll tax cut extension passed by the United States Congress on February 17, 2012. Background The 2008 United States wireless spectrum auction, dealing with allocations for UHF television in the 700 MHz band, generated $19.6 billion from companies such as AT&T and Verizon Communications. This auction re-allocated the UHF space formerly occupied by channels 52–69, after the completion of the primary digital television transition in the United States from NTSC to ATSC in 2009. In effect, the digital transition had eliminated 25% of the space allocated for UHF television in the United States. Wireless broadband internet access intere ...
