RadioThe Radio industry brings channels over frequency broadcasting to people over the area.

History of RadioThe early history of radio is the history of technology that produced radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of programming and content.

The idea of wireless communication predates the discovery of "radio" with experiments in "wireless telegraphy" via inductive and capacitive induction and transmission through the ground, water, and even train tracks from the 1830s on. In 1873 James Clerk Maxwell showed mathematically that electromagnetic waves could propagate through free space. It is likely that the first intentional transmission of a signal by means of electromagnetic waves was performed in an experiment by David Edward Hughes around 1880, although this was considered to be induction at the time. In 1888 Heinrich Rudolf Hertz was able to conclusively prove transmitted airborn electromagnetic waves in an experiment confirming Maxwell's theory of electromagnetism.

Around the start of the 20th century, the Slaby-Arco wireless system was developed by Adolf Slaby and Georg von Arco. In 1900, Reginald Fessenden made a weak transmission of voice over the airwaves. In 1901, Marconi conducted the first successful transatlantic experimental radio communications. In 1904, The USA Patent Office reversed its decision, awarding Marconi a patent for the invention of radio, possibly influenced by Marconi's financial backers in the States, who included Thomas Edison and Andrew Carnegie.

In 1954 Regency introduced a pocket transistor radio, the TR-1, powered by a "standard 22.5V Battery". In the early 1960s, VOR systems finally became widespread for aircraft navigation; before that, aircraft used commercial AM radio stations for navigation. (AM stations are still marked on U.S. aviation charts). In 1960 Sony introduced their first transistorized radio, small enough to fit in a vest pocket, and able to be powered by a small battery. It was durable, because there were no tubes to burn out. Over the next twenty years, transistors displaced tubes almost completely except for picture tubes and very high power or very high frequency uses.

Many Radio Stations make profit via adverts However the BBC do it another way with no adverts.

How do they make Profit?Advertisements are the main resources of the radio stations. Why do you think the music's we hear at the radio are always stop by an advertisement each thirty or forty minutes for a quarter hour. For the radios that have not adverts, it is simple : they do not play the whole music until the end or cut it. it depends on the station and how it is set up. in the world at large, the number one way of financing is via the government - increasingly with more commercial input as well in the form of ads. in developed countries, commercials are the main way that commercial radio makes money. there are also non-commercial stations - these can be linked to the state, or a community group, a university, or otherwise be independent. these stations rely on fundraisers, and acknowledgements (basically ads) for funding. in some countries, there exists a tax for the broadcasting industry - this may be to help the government fund their stations, or it may go to an independent body that then distributed the monies to the interested parties. for satellite radio - it's a combination of subscription fees and ads. for internet radio - who knows? it really is varied there and the models are all different. it could be one person spending out of their pockets - or small groups with a message - or big corporations that want to be on the web...

The meaning of radio licensable content service is set out in sections 245 to 248 of the Communications Act 2003. Radio licensable content service (“RLCS”)licences replace the separate categories of satellite service licences and licensable sound programme service licences (i.e. cable) which were established under the Broadcasting Act 1990.

A radio licensable content service is a service provided in digital or analogue form broadcast from a satellite or distributed using an electronic communications network that is to be made available for reception by members of the public and consists of sound programmes.

In broad terms, radio licensable content services do not include internet services or two-way services. Further, they do not include a service which is distributed by means of an electronic communications network only to persons who are within a single set of premises, and not connected to an electronic communications network any part of which is outside those premises. Neither do they include services which are provided only for persons who have a business interest in the programmes included in the service or persons who are all on the business premises of the person receiving the service.

Ofcom’s statutory function with regard to radio licensable content service licensing is laid out in section 245 of the Communications Act 2003. To fall within the scope of this section, an RLCS would have to be either:(a) provided from a place within the UK; or(b) provided by a person whose principal place of business is in the UK; or(c) uplinked in the UK and not licensed under the laws of another EEA state.

For Radio Licensable Content Service Licences, one licence is necessary per service rather than per company or individual. There is no restriction on the number of licences which can be held by an individual or company.

A service will be licensable if it falls within one of the statutory licence definitions in the Communications Act 2003. Applicants are responsible for assessing whether a service requires a licence. They may wish to take their own professional advice in order to comply with this obligation

Radio RolesResearchers research the project ahead of shooting time to increase truth, factual content, creative content, original ideas, background information, and sometimes performs minor searches such as flight details, location conditions, accommodation details, etc.

A Writer creates and moulds an original story, or adapts other written, told, or acted stories for production of a television show. Their finished work is called a script. A script may also have been a contribution of many writers,

The editor works in tandem with the director to edit raw footage into a finished work. The director has ultimate accountability for editing choices, but often the editor has substantial contribution in the creative decisions concerned in piecing together a finalized product

A radio presenter is a personality who appears in on-air position in radio broadcasting. A radio personality can be someone who introduces and discusses various genres of music, hosts a Talk radio show that may take calls from listeners, or someone whose primary responsibility is to give news, weather, sports, or traffic information.
