The station's newscasts have used the same theme music, "Move Closer to Your World", composed by Al Ham, since October 1, 1972. The theme had become such an iconic aspect of "Action News" that news director Dave Davis considered it to be the station's "national anthem". The theme has remained relatively unchanged (aside from remasters) since it was first introduced; when WPVI attempted to introduce a slower, modernized version of the theme performed by the London Philharmonic Orchestra on September 20, 1996, the station immediately received complaints from viewers and reverted to the old theme only three days later. The intro has traditionally been accompanied by seasonal footage of various Philadelphia/Delaware Valley residents and landmarks. Later the intro format was adopted by sister stations KGO-TV and WLS-TV with the News Series 2000 Plus theme music. For over 30 years starting in the late 1970s, Jefferson "Jeff" Kaye (also a WKBW alumnus, and one who would later become known nationally for his work on NFL Films) announced the familiar open: "Action News, Delaware Valley's leading news program", as well as rejoins and closings. Even through staff announcing changes for the station in general, Kaye remained the constant voice of "Action News". His voice started to show signs of decaying in the mid-2000s, reaching a point to where Kaye's newly recorded opens in late January 2010 were pulled in less than a week. On June 21, 2010, Kaye was replaced with veteran announcer Charlie Van Dyke, who had become WPVI's station announcer in 2006. Kaye died on November 16, 2012.
