Illustrated song in the context of Nickelodeon (movie theater)

Vaudeville (/ˈvɔːd(ə)vɪl, ˈvoʊ-/; French: [vodvil] ) is a theatrical genre of variety entertainment which became popular in the United States and Canada from the early 1870s until the early 1930s.

In some ways analogous to music hall from Victorian Britain, a typical North American vaudeville performance was made up of a series of separate, unrelated acts grouped together on a common bill. Types of acts have included popular and classical musicians, singers, dancers, comedians, trained animals, magicians, ventriloquists, strongmen, female and male impersonators, acrobats, clowns, mimes, illustrated songs, jugglers, athletes, lecturing celebrities, or scenes from plays, one-act plays, minstrels, and films. A vaudeville performer is often referred to as a "vaudevillian."

A hit song, also known as a hit record, hit single, or simply hit, is a recorded song or instrumental that becomes broadly popular or well-known. Although hit song means any widely played or big-selling song, the specific term hit record usually refers to a single that has appeared in an official music chart through repeated radio airplay audience impressions or significant streaming data and commercial sales.

Prior to the dominance of recorded music, commercial sheet music sales of individual songs were similarly promoted and tracked as singles and albums are now. For example, in 1894, Edward B. Marks and Joe Stern released The Little Lost Child, which sold more than a million copies nationwide, based mainly on its success as an illustrated song, analogous to what later became music videos.

A music video is a video that integrates a song or an album with imagery that is produced for promotional or musical artistic purposes. Modern music videos are primarily made and used as a music marketing device intended to promote the sale of music recordings. These videos are typically shown on music television and on streaming video sites like YouTube, or more rarely shown theatrically. They can be commercially issued on home video, either as video albums or video singles. The format has been described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip", "film clip", "video clip", or simply "video".

While musical short films were popular as soon as recorded sound was introduced to theatrical film screenings in the 1920s, promotional music videos started becoming popular into the 1960s and the music video rose to prominence in the 1980s when American TV channel MTV based its format around the medium.
