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, Canada and Australia 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.
