The hertz ( symbol : Hz ) is the derived unit of frequency in the International System of Units ( SI ) and is defined as one cycle per second . It is named after Heinrich Rudolf Hertz , the first person to provide conclusive proof of the existence of electromagnetic waves . Hertz are commonly expressed in multiples : kilohertz ( 103 Hz , kHz ) , megahertz ( 106 Hz , MHz ) , gigahertz ( 109 Hz , GHz ) , terahertz ( 1012 Hz , THz ) , petahertz ( 1015 Hz , PHz ) , exahertz ( 1018 Hz , EHz ) , and zettahertz ( 1021 Hz , ZHz ) . Some of the unit 's most common uses are in the description of sine waves and musical tones , particularly those used in radio- and audio-related applications . It is also used to describe the clock speeds at which computers and other electronics are driven . The units are sometimes also used as a representation of energy , via the photon energy equation ( E=hν ) , with one hertz equivalent to h joules .

It began transmission on 2 November 1982 . Although largely commercially self-funded , it is ultimately publicly owned ; originally a subsidiary of the Independent Broadcasting Authority ( IBA ) , the station is now owned and operated by Channel Four Television Corporation , a public corporation of the Department for Digital , Culture , Media and Sport , which was established in 1990 and came into operation in 1993 . In 2010 , Channel 4 extended service into Wales and became a UK-wide television channel .
BBC One ( or BBC1 and BBC 1 ) is the first and flagship television channel of the BBC in the United Kingdom , Isle of Man and Channel Islands . It was launched on 2 November 1936 as the BBC Television Service , and was the world 's first regular television service with a high level of image resolution . It was renamed BBC TV in 1960 , using this name until the launch of the second BBC channel BBC2 in 1964 , whereupon the BBC TV channel became known as BBC1 , with the current spelling adopted in 1997 . The channel 's annual budget for 2012-13 was £1.14 billion . The channel is funded by the television licence fee together with the BBC 's other domestic television stations , and shows uninterrupted programming without commercial advertising . It is currently the most watched television channel in the United Kingdom , ahead of its traditional rival for ratings leadership , ITV .

ITV is a British free-to-air television channel . Previously a network of separate uniquely identifiable regional television channels , ITV currently operates in England , Wales , Scotland , the Isle of Man , and the Channel Islands . From 2001 until 2013 , the primary ITV channel was called ITV1 . In 2004 , Granada Television acquired Carlton Communications to form ITV plc . ITV is the biggest and most popular commercial television channel in the United Kingdom . ITV , and its predecessor channels have contended with BBC One for the status of the UK 's most watched television channel since the 1950s . However , in line with other terrestrial channels , ITV 's audience share has fallen as a result of availability of multi-channel television in the UK .
BBC Two is the second flagship television channel of the British Broadcasting Corporation ( BBC ) in the United Kingdom , the Isle of Man and the Channel Islands . It covers a wide range of subject matter , but tends to broadcast more highbrow programmes than 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-service network , regularly attaining a much higher audience share than most public-service networks worldwide . Originally styled BBC2 , it was the third British television station to be launched ( starting on 20 April 1964 ) , and from 1 July 1967 , Europe 's first television channel to broadcast regularly in colour . It was envisaged as a home for less mainstream and more ambitious programming , and while this tendency has continued to date , most special-interest programmes of a kind previously broadcast on BBC Two , for example the BBC Proms , now tend to appear on BBC Four instead .
Digital 3 & 4 is a consortium consisting of ITV plc , STV Group plc and the Channel Four Television Corporation , which operates a multiplex broadcasting from a number of transmitter sites in the United Kingdom , carrying television and radio channels , together with interactive services , from both ITV and Channel 4 . Unlike other multiplexes , the regional ITV broadcaster has control over which services are to be broadcast on their allotted amount of the capacity , leading to small regional differences across the country .
