With Steigerwalds departure in 1999, Mike Lange shared the broadcast booth with former Penguins defenseman Peter Taglianetti. Taglianetti, a two-time Stanley Cup winner with the team in 1991 and 1992, remained in the position for one season before being replaced by Ed Olczyk. Lange and Olczyk were broadcast partners from 2000 until 2003, when Olczyk left the booth to become the 18th head coach in Penguins history that had become upon due to the firing of previous Head Coach Rick Kehoe after the 2002–03 season. With Olczyks vacancy, the Penguins hired Bob Errey as their new color commentator for the start of the 2003–04 season (a position that he continues to hold as of the start of the 2012–13 season. Lange and Errey remained in the booth until 2005–06. After 26 seasons in the television broadcast booth, Mike Lange was not retained by FSN Pittsburgh. Instead, he was replaced by former broadcast partner Paul Steigerwald, who remained the TV play-by-play broadcaster for the team until the 2016–17 season. Lange returned to the radio broadcast booth and currently holds the position of radio play-by-play announcer, the same position he had held with the team in the mid-1970s. Following the 2016–17 season, Steigerwald moved back to the Penguins front office and NHL Network (U.S. TV network) personality Steve Mears was hired as the new television play-by-play announcer starting with the 2017–18 season.
