Others ask only new music be played, to help promote their latest release, even when an older song would be more appropriate to the segment. Even when a well-known artist does allow usage, the budgets of many shows are not designed for major music expenditures. Therefore, one high profile artist can use up most of the budget thereby leaving the door open to unknowns for the remainder of episode's music needs. By using the music of struggling artists shows get needed music at a budget conscious price, and the artist gets exposure. This creates a win-win situation for both parties.
Some network shows even have a log containing information about the music used on shows.
Shows often need instrumental background music, and are often willing to take portions of a song that has the right groove. You can often get interest by creating instrumental versions of your songs, which should be about two minutes in length , to create pieces that they would want to incorporate in their productions. Once you have music you feel is appropriate for television, whether a particular show or just background music in general, you have to get it to people who make the decisions about what will be used. Most shows have a music director, and by calling the networks, you can get information about who works for which shows. You will be surprised at how willing many of them will be to listen to your music.
