The year 1958 in television involved some significant events. Below is a list of television-related events during 1958.
Regular television broadcasts in the United Kingdom started in 1936 as a public service which was free of advertising, which followed the first demonstration of a transmitted moving image in 1926. Currently, the United Kingdom has a collection of free-to-air, free-to-view and subscription services over a variety of distribution media, through which there are over 480 channels for consumers as well as on-demand content. There are six main channel owners who are responsible for most material viewed.
Terrestrial television or over-the-air television (OTA) is a type of television broadcasting in which the signal transmission occurs via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna. The term terrestrial is more common in Europe and Latin America, while in Canada and the United States it is called over-the-air or simply broadcast. This type of TV broadcast is distinguished from newer technologies, such as satellite television, in which the signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and UHF bands. Since radio waves in these bands travel by line of sight, reception is generally limited by the visual horizon to distances of 64–97 kilometres (40–60 mi), although under better conditions and with tropospheric ducting, signals can sometimes be received hundreds of kilometers distant.
Television in Hong Kong is primarily in Cantonese and English. It is delivered through analogue and digital terrestrial, cable, IPTV, and the Internet. Satellite TV is not common, although many housing estates have dishes and re-distribute a limited number of free channels through coaxial cables. The dominant broadcaster is TVB and ViuTV.
Iowa PBS, formerly Iowa Public Television (IPTV), is a network of Public Broadcasting Service (PBS) member stations in the U.S. state of Iowa. It is operated by the Iowa Public Broadcasting Board, an agency of the state education department which holds the licenses for all the PBS member stations in the state. Iowa PBS' headquarters are located at 6450 Corporate Drive in Johnston, Iowa, a suburb of Des Moines.
Digital terrestrial television is a technology for terrestrial television in which land-based (terrestrial) television stations broadcast television content by radio waves to televisions in consumers' residences in a digital format. DTTV is a major technological advance over the previous analog television, and has largely replaced analog television broadcast, which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV beginning in 2006 and is now complete in many countries. The advantages of digital terrestrial television are similar to those obtained by digitising platforms such as cable TV, satellite, and telecommunications: more efficient use of limited radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters.
The Turkish Radio and Television Corporation is the national public broadcaster of Turkey, founded in 1964. TRT was for many years the only television and radio provider in Turkey. Before the introduction of commercial radio in 1990, and subsequently commercial television in 1992, it held a monopoly on broadcasting. More recent deregulation of the Turkish television broadcasting market produced analogue cable television. Today, TRT broadcasts around the world, especially in Europe, Middle East, Africa, Asia, USA, and Australia.
The Swiss Broadcasting Corporation is the Swiss public broadcasting association, founded in 1931, the holding company of 26 radio and television channels. Headquartered in Bern, the Swiss Broadcasting Corporation is a non-profit organisation, funded mainly through radio and television licence fees (70%) and making the remaining income from advertising and sponsorship.
The Asahi Broadcasting Group Holdings Corporation is a certified broadcasting holding company headquartered in Osaka, Japan.

The concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass medium for advertising, propaganda, and entertainment.
Television in Bulgaria was introduced in 1959. Global players such as News Corporation, Modern Times Group, Central European Media Enterprises, Fox Broadcasting Company and others operate the biggest and most popular media outlets in the country.
Television in Italy was introduced in 1939, when the first experimental broadcasts began. However, this lasted for a very short time: when fascist Italy entered World War II in 1940, all transmissions were interrupted, and were resumed in earnest only nine years after the end of the war, on January 3, 1954.
High-definition television (HDTV) describes a television or video system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television.
441-line is the number of scan lines in some early electronic monochrome analog television systems. Systems with this number of lines were used with 25 interlaced frames per second in France from 1937 to 1956, Germany from 1939 to 1943, Italy from 1939 to 1940, as well as by RCA in the United States with 30 interlaced frames per second from 1938 to 1941. Broadcasts were planned in Finland for 1940, but eventually cancelled due to World War II. Some experiments with similar systems were carried out on the USSR in the 1930s and Japan in 1939.
Television in Croatia was first introduced in 1956. As of 2012, there are 10 nationwide and 21 regional DVB-T television channels, and there are more than 30 other channels either produced in the Republic of Croatia or produced for the Croatian market and broadcast via IPTV, cable, or satellite television. The electronic communications market in Croatia is regulated by the Croatian Regulatory Authority for Network Industries (HAKOM), which issues broadcast licenses and monitors the market. The DVB-T and satellite transmission infrastructure is developed and maintained by the state-owned company Odašiljači i veze (OiV).
