News Report
The news media or news industry are forms of mass media that focus on delivering news to the general public. These include news agencies, newspapers, news magazines, news channels etc. History Some of the first news circulations occurred in Renaissance Europe. These handwritten newsletters, circulated among merchants, contained news about wars, economic conditions, and social customs. Newsletters were very scarce and no two were the same as they were all hand written, until the invention of the printing press by Johannes Gutenberg in 1440. With movable type and ink, newspapers were now able to be mass produced for cheap. The first printed news appeared by the late 1400s in German pamphlets, which contained content that was often highly sensationalized. The first newspaper written in English was ''The Weekly News,'' published in London in 1621. Several papers followed in the 1640s and 1650s. In 1690, the first American newspaper was published by Richard Pierce and Benjamin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printing Press
A printing press is a mechanical device for applying pressure to an inked surface resting upon a printing, print medium (such as paper or cloth), thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper, or other medium was brushed or rubbed repeatedly to achieve the transfer of ink and accelerated the process. Typically used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. In Germany, around 1440, the goldsmith Johannes Gutenberg invented the movable type, movable-type printing press, which started the Printing Revolution. Modelled on the design of existing screw presses, a single Renaissance movable-type printing press could produce up to 3,600 pages per workday, compared to forty by History of typography in East Asia, hand-printing and a few by scribe, hand-copying. Gutenberg's newly devised hand mould made possible the precise and rapi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Radio
Digital radio is the use of digital technology to transmit or receive across the radio spectrum. Digital transmission by radio waves includes digital broadcasting, and especially digital audio radio services. This should not be confused with Internet radio which also is digital but not transmitted by radio waves in the radio spectrum. Types In digital broadcasting systems, the analog audio signal is digitized, compressed using an audio coding format such as AAC+ ( MDCT) or MP2, and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional datacasting services, and to decrease the transmission power or the number of transmitters required to cover a region. However, analog radio (AM and FM) is still more popular and listening to radio over IP (Internet Protocol) is growing in popularity. In 2012, four dig ...

BBC Two
BBC Two is a British free-to-air Public service broadcasting in the United Kingdom, public broadcast television channel owned and operated by the BBC. It is the corporation's second flagship channel, and it covers a wide range of subject matter, incorporating genres such as comedy, drama and documentaries. BBC Two has a remit "to broadcast highbrow, programmes of depth and substance" in contrast to the more mainstream and popular BBC One. Like the BBC's other domestic TV and radio channels, it is funded by the television licence, and is therefore free of commercial advertising. It is a comparatively well-funded Public broadcasting, public-service channel, regularly attaining a much higher audience share than most public-service channels worldwide. Originally styled BBC2, it was the third British television station to be launched (starting on 21 April 1964), and from 1 July 1967, Europe's first television channel to broadcast regularly in colour. It was envisaged as a home for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC One
BBC One is a British free-to-air public broadcast television channel owned and operated by the BBC. It is the corporation's oldest and flagship channel, and is known for broadcasting mainstream programming, which includes BBC News television bulletins, primetime drama and entertainment, and live BBC Sport events. The channel was launched on 2 November 1936 under the name BBC Television Service, which was the world's first regular television service with a high level of image resolution. It was renamed BBC TV in 1960 and used this name until the launch of the second BBC channel, BBC2, in 1964. The main channel then became known as BBC1. The channel adopted the current spelling of BBC One in 1997. The channel's annual budget for 2012–2013 was £1.14 billion. It is funded by the television licence fee together with the BBC's other domestic television stations and shows uninterrupted programming without commercial advertising. The television channel had the highest reach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequencies
Frequency is the number of occurrences of a repeating event per unit of time. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light. The interval of time between events is called the period. It is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times per minute (2 hertz), its period is one half of a second. Special definitions of frequency are used in certain contexts, such as the angular frequency in rotational or cyclical properties, when the rate of angular progress is measured. Spatial frequency is defined for properties that vary or cccur repeatedly in geometry or space. The unit of measurement of frequency in the International System of Units (SI) is the hertz, having the symbol Hz. Definitions and units For cyclical phenomena such as oscillations, waves, or for examples ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organization
An organization or organisation (English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-ise, -ize (-isation, -ization), see spelling differences) is an legal entity, entity—such as a company, or corporation or an institution (formal organization), or an Voluntary association, association—comprising one or more person, people and having a particular purpose. Organizations may also operate secretly or illegally in the case of secret society , secret societies, criminal organizations, and resistance movements. And in some cases may have obstacles from other organizations (e.g.: Southern Christian Leadership Conference, MLK's organization). What makes an organization recognized by the government is either filling out Incorporation (business), incorporation or recognition in the form of either societal pressure (e.g.: Advocacy group), causing concerns (e.g.: Resistance movement) or being considered the spokesperson o ...

Scheduling (broadcasting)
Broadcast programming is the practice of organizing or ordering (scheduling) of Broadcasting, broadcast media shows, typically radio and television, in a daily, weekly, monthly, quarterly, or season-long schedule. Modern broadcasters use broadcast automation to regularly change the scheduling of their shows to build an audience for a new show, retain that audience, or compete with other broadcasters' shows. Most broadcast television shows are presented weekly in prime time or daily in other dayparts, though there are many exceptions. At a micro level, scheduling is the minute planning of the transmission; what to broadcast and when, ensuring an adequate or maximum utilization of airtime. Television scheduling strategies are employed to give shows the best possible chance of attracting and retaining an audience. They are used to deliver shows to audiences when they are most likely to want to watch them and deliver audiences to advertisers in the composition that makes their adve ...

Pay-per-view
Pay-per-view (PPV) is a type of pay television or webcast service that enables a viewer to pay to watch individual events via private telecast. Events can be purchased through a multichannel television platform using their electronic program guide, an automated telephone system, or through a live customer service representative. There has been an increasing number of PPVs distributed via streaming video online, either alongside or in lieu of carriage through television providers. In 2012, the popular video sharing platform YouTube began to allow partners to host live PPV events on the platform. Events distributed through PPV typically include boxing, mixed martial arts, professional wrestling, and concerts. In the past, PPV was often used to distribute telecasts of feature films, as well as adult content such as pornographic films, but the growth of digital cable and streaming media caused these uses to be subsumed by video on demand systems (which allow viewers to purchas ...

Subscription
The subscription business model is a business model in which a customer must pay a recurring price at regular intervals for access to a product or service. The model was pioneered by publishers of books and periodicals in the 17th century. It is particularly common now for digital products, which lend themselves more naturally toward a subscription model. Subscriptions can be a more convenient, hassle-free transaction for consumers. However, due to inertia among some consumers, they may inadvertently pay for subscriptions that they no longer value because they do not realize that they are subscribed. Subscriptions Rather than selling products individually, a subscription offers periodic (daily, weekly, bi-weekly, monthly, semi-annual, yearly/annual, or seasonal) use or access to a product or service, or, in the case of performance-oriented organizations such as opera companies, tickets to the entire run of some set number of (e.g., five to fifteen) scheduled performances for ...

Descrambler
In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the Digital data, digital domain, scrambling usually refers to operations carried out in the Analog transmission, analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation. In telecommunications and ...

Cable Television
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna, or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A cable channel (sometimes known as a cable network) is a television network available via cable television. Many of the same channels are distributed throug ...
