Commercial broadcasting (also called private broadcasting) is the broadcasting of television programs and radio programming by privately owned corporate media, as opposed to state sponsorship, for example. It was the United States' first model of radio (and later television) during the 1920s, in contrast with the public television model during the 1930s, 1940s, and 1950s, which prevailed worldwide, except in the United States, Mexico, and Brazil, until the 1980s.
Features
Advertising
Commercial broadcasting is primarily based on the practice of airing radio advertisements and television advertisements for profit. This is in contrast to public broadcasting, which receives government subsidies and usually does not have paid advertising interrupting the show. During pledge drives, some public broadcasters will interrupt shows to ask for donations.
Radio broadcasting originally began without paid commercials. As time went on, however, advertisements seemed less objectionable to both the public and government regulators and became more common. While commercial broadcasting was unexpected in radio, in television it was planned due to commercial radio's success. Television began with commercial sponsorship and later transformed to paid commercial time. When problems arose over patents and corporate marketing strategies, regulatory decisions were made by the Federal Communications Commission (FCC) to control commercial broadcasting.[1]
Paid programming
Commercial broadcasting overlaps with paid services such as cable television, radio and satellite television. Such services are generally partially or wholly paid for by local subscribers and is known as leased access. Other programming (particularly on cable television) is produced by companies operating in much the same manner as advertising-funded commercial broadcasters, and they (and often the local cable provider) sell commercial time in a similar manner.
The FCC's interest in program control began with the chain-broadcasting investigation of the late 1930s, culminating in the "Blue Book" of 1946, Public Service Responsibility For Broadcast Licensees. The Blue Book differentiated between mass-appeal sponsored programs and unsponsored "sustaining" programs offered by the radio networks. This sustained programming, according to the Blue Book, had five features serving the public interest:
Sustaining programs balanced the broadcast schedule, supplementing the soap operas and popular-music programs receiving the highest ratings and most commercial sponsors
They allowed for the broadcast of programs which, by their controversial or sensitive nature, were unsuitable for sponsorship
They supplied cultural programming for smaller audiences
They provided limited broadcast access for non-profit and civic organizations
They made possible artistic and dramatic experimentation, shielded from the pressures of short-run rating and commercial considerations of a sponsor.[1]
Commercial time has increased 31 seconds per hour for all prime time television shows. For example, ABC has increased from 9 minutes and 26 seconds to 11 minutes and 26 seconds.[2]
Ratings
Programming on commercial stations is more ratings-driven—particularly during periods such as sweeps in the US and some Latin American countries.
Global commercial broadcasting
Americas
Commercial broadcasting is the dominant type of broadcasting in the United States and most of Latin America. "The US commercial system resulted from a carefully crafted cooperation endeavor by national corporations and federal regulators."[3]
In an hour of broadcast time on a commercial broadcasting station, 10 to 20 minutes are typically devoted to advertising. Advertisers pay a certain amount of money to air their commercials, usually based upon program ratings or the audience measurement of a station or network. This makes commercial broadcasters more accountable to advertisers than public broadcasting, a disadvantage of commercial radio and television.
Europe
In Europe, commercial broadcasting coexists with public broadcasting (where programming is largely funded by broadcast receiver licenses, public donations or government grants).
In the UK, Sky UK is available and WorldSpace Satellite Radio was available.
Asia
The best and most known commercial broadcasters in Asia are the South Korean radio and television networks SBS, Hong Kong television networks TVB, Taiwanese television networks FTV and Philippine radio and television networks GMA Network.
