Please answer the following question: Information: - A radio format or programming format (not to be confused with broadcast programming) describes the overall content broadcast on a radio station. Radio formats are frequently employed as a marketing tool, and are subject to frequent change. Music radio, old time radio, all-news radio, sports radio, talk radio and weather radio describe the operation of different genres of radio format and each format can often be sub-divided into many specialty formats. - Your Hit Parade is an American radio and television music program that was broadcast from 1935 to 1955 on radio, and seen from 1950 to 1959 on television. It was sponsored by American Tobacco's Lucky Strike cigarettes. During this 24-year run, the show had 19 orchestra leaders and 52 singers or groups. Many listeners and viewers casually referred to the show with the incorrect title The Hit Parade. - Television or TV is a telecommunication medium used for transmitting moving images in monochrome (black-and-white), or in color, and in two or three dimensions and sound. It can refer to a television set, a television program ("TV show"), or the medium of television transmission. Television is a mass medium, for entertainment, education, news, and advertising. - In radio broadcasting, airplay is how frequently a song is being played on radio stations. A song which is being played several times every day (spins) would have a large amount of airplay. Music which became very popular on jukeboxes, in nightclubs and at discotheques between the 1940s and 1960s would also have airplay. - Popular music is music with wide appeal that is typically distributed to large audiences through the music industry. These forms and styles can be enjoyed and performed by people with little or no musical training. It stands in contrast to both art music and traditional or "folk" music. Art music was historically disseminated through the performances of written music, although since the beginning of the recording industry, it is also disseminated through recordings. Traditional music forms such as early blues songs or hymns were passed along orally, or to smaller, local audiences. - Contemporary hit radio (also known as CHR, contemporary hits, hit list, current hits, hit music, top 40, or pop radio) is a radio format that is common in the United States, United Kingdom, Ireland, Canada, New Zealand, Australia, Singapore and South Africa that focuses on playing current and recurrent popular music as determined by the top 40 music charts. There are several subcategories, dominantly focusing on rock, pop, or urban music. Used alone, "CHR" most often refers to the CHR-pop format. The term "contemporary hit radio" was coined in the early 1980s by "Radio & Records" magazine to designate top 40 stations which continued to play hits from all musical genres as pop music splintered into adult contemporary, urban contemporary and other formats. - A record chart is a ranking of recorded music according to popularity during a given period of time . Examples of music charts are the Hit parade , the Billboard Hot 100 or Top 40 . Many different criteria are used in different charts , including sales of records , cassettes and compact discs , the amount of radio airplay , and since the introduction of digital technology , the number of downloads and the amount of streaming activity . Some charts are specific to a particular musical genre and most to a particular geographical location ( although download charts are not easily pinned down in this way ) . The most common period of time covered by a chart is one week with the chart being printed or broadcast at the end of this time . Summary charts for years and decades are then calculated from their component weekly charts . Component charts have become an increasingly important way to measure the commercial success of individual songs . - Top 40 is a music industry shorthand for the currently most-popular songs in a particular genre. When used without qualification it refers to the best-selling or most frequently broadcast popular music. The term is derived from record music charts, a few of which traditionally consist of a total of 40 songs. Top 40 is also an alternative term for the radio format of such music, also known as Contemporary hit radio. - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form. - A hit parade is a ranked list of the most popular recordings at a given point in time, usually determined by sales and/or airplay. The term originated in the 1930s; "Billboard" magazine published its first music hit parade on January 4, 1936. It has also been used by broadcast programs which featured hit (sheet music and record) tunes such as "Your Hit Parade", which aired on radio and television in the United States from 1935 through the 1950s.
