Radio format in the context of "Urban contemporary"

Talk radio is a radio format containing discussion about topical issues and consisting entirely or almost entirely of original spoken word content rather than outside music. They may feature monologues, dialogues between the hosts, interviews with guests, and/or listener participation which may be live conversations between the host and listeners who "call in" (usually via telephone) or via voice mail. Listener contributions are usually screened by a show's producers to maximize audience interest and, in the case of commercial talk radio, to attract advertisers.

Talk shows on commercial stations are organized into segments, each separated by a pause for advertisements; however, in public or non-commercial radio, music is sometimes played in place of commercials to separate the program segments.

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.
