Television in Japan

Television broadcasting in Japan started in 1950, making the country one of the first in the world with an experimental television service, although the first television tests were conducted as early as 1926 using a combined mechanical Nipkow disk and electronic Braun tube system, later switching to an all-electronic system in the 1930s using a domestically developed iconoscope system. In spite of that, because of the beginning of World War II in the Pacific region, this first full-fledged TV broadcast experimentation lasted only a few months. Regular television broadcasts only started several years after the war, in 1953, when the public NHK General TV and the commercial Nippon Television were launched in the span of a few months.

A modified version of the North American NTSC system for analog signals, called NTSC-J was used for analog broadcast until 2011. Starting July 24, 2011, the analog broadcast has ceased and only digital broadcast using the ISDB standard is available.

Television advertisement

A television advertisement (variously called a television commercial, commercial or ad in American English, and known in British English as an advert) is a span of television programming produced and paid for by an organization, which conveys a message, typically to market a product or service. Advertising revenue provides a significant portion of the funding for most privately owned television networks. The vast majority of television advertisements today consist of brief advertising spots, ranging in length from a few seconds to several minutes (as well as program-length infomercials). Advertisements of this sort have been used to promote a wide variety of goods, services and ideas since the beginning of television.

The effects of television advertising upon the viewing public (and the effects of mass media in general) have been the subject of philosophical discourse by such luminaries as Marshall McLuhan. The viewership of television programming, as measured by companies such as Nielsen Media Research, is often used as a metric for television advertisement placement, and consequently, for the rates charged to advertisers to air within a given network, television program, or time of day (called a "daypart").
