"Posthumus Zone" and "Granicus" are songs composed by the now-disbanded Los Angeles electronic music group E.S. Posthumus for the TV programs NFL on CBS and The NFL Today on CBS Sports. The songs are played at the start and end of the programs, before and after commercial breaks, and during stoppages on the NFL on CBS play games, and on commercial spots that announce the programming schedule, as a jingle for viewers to remember. The theme was first used for the NFL on CBS in 2003.
