As corporate ownership of radio stations increased, so did the use of similar playlists. This was due to several factors:
* The desire to appeal to a wide audience: Corporate radio stations are profit-driven, so they aim to appeal to the largest possible audience. By playing similar music, these stations can attract listeners who are interested in the same genres and artists.
* The efficiency of syndicated programming: Syndicated programming involves producing radio shows or segments that are then distributed to multiple stations. This allows stations to save money on production costs while still providing listeners with a variety of content. Syndicated programs often have their playlists, which further encourages stations to play similar music.
* The influence of major record labels: Major record labels have a significant amount of power in the music industry, and they can influence radio stations' playlists. By promoting their artists and songs to radio stations, record labels can increase their sales and exposure. This can lead to a situation where radio stations play a narrow range of music that is dictated by the major labels.
The homogenization of radio playlists has several consequences. It reduces listeners' options and encourages musical conformity. It also makes it more difficult for new and independent artists to get their music heard on the radio. This has led to criticism of corporate radio stations and calls for more diversity in radio programming.
