Radio format in the context of "Talk radio"

Contemporary hit radio (CHR, also known as contemporary hits, hit list, current hits, hit music, top 40, or pop radio) is a radio format common in many countries 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, contemporary Christian and other formats.

The term "top 40" is also used to refer to the actual list of hit songs, and, by extension, to refer to pop music in general. The term has also been modified to describe top 50; top 30; top 20; top 10; hot 100 (each with its number of songs) and hot hits radio formats, but carrying more or less the same meaning and having the same creative point of origin with Todd Storz as further refined by Gordon McLendon as well as Bill Drake. The format became especially popular in the mid-sixties as radio stations constrained disc jockeys to numbered play lists in the wake of the payola scandal.

Adult contemporary (AC) is category of popular music catered to adult demographics, including record charts and radio formats that are focused on such music.

The exact assemblage of adult contemporary music has varied based on trends in popular music, but has usually encompassed songs within genres popular among audiences that had grown out of music that appeals more to youth and young adult audiences. Adult contemporary was originally established as a continuation of the easy listening and soft rock sounds from the 1960s and 1970s, usually focusing on songs with varying degrees of easy listening, pop, soul, R&B, quiet storm, and rock influence. In the 1990s, adult contemporary began to accommodate a hotter sound more inclusive of contemporary pop songs, and develop sub-categories devoted towards specific genres.

Urban contemporary music, also known as urban music, urban pop, or just simply urban, is a music radio format. The term was coined by New York radio DJ Frankie Crocker in the early to mid-1970s as a synonym for Black music. Urban contemporary radio stations feature a playlist made up entirely of Black genres such as R&B, pop rap, quiet storm, urban adult contemporary and hip hop; Latin music such as Latin pop, Chicano R&B and Chicano rap; and Caribbean music such as reggae and soca. Urban contemporary was developed through the characteristics of genres such as R&B and soul.

Because urban music is a largely U.S. phenomenon, virtually all urban contemporary formatted radio stations in the United States are located in cities that have sizeable African-American populations, such as New York City; Washington, D.C.; Detroit; Atlanta; Miami; Chicago; Cleveland; Philadelphia; Pittsburgh; Montgomery; Memphis; St. Louis; Newark; Charleston; New Orleans; Milwaukee; Cincinnati; Dallas; Houston; Oakland; Sacramento; Los Angeles; Trenton; Columbia; Jacksonville; Flint; Baltimore; Boston; Birmingham; Indianapolis; Augusta; Richmond; Charlotte; Savannah; Hartford; and Jackson.

All-news radio is a radio format devoted entirely to the discussion and broadcast of news.

All-news radio is available in both local and syndicated forms, and is carried on both major US satellite radio networks. All-news stations can run the gamut from simulcasting an all-news television station like CNN, to a "rip and read" headline service, to stations that include live coverage of news events and long-form public affairs programming.

Radio programming is the process of organising a schedule of radio content for commercial broadcasting and public broadcasting by radio stations.
