"There have been a number of dramatic changes in the game," said Steve Tello, vice president and general manager of FSN Pittsburgh.
"With the new changes with the players on the ice, the management on the ice and possibly even new owners, we thought this was the time to give Paul the opportunity to move to the TV side," Tello said.
"Paul and (color commentator) Bob Errey were a team on the radio and did a terrific job. We feel that Paul is well suited to what we are trying to do with the game," Tello said.
"Mike has done a terrific job over the years, as has Paul. This is more about Paul's hard work and not a comment on Mike Lange. This is not a political decision. This is a television production decision."
Tello said he hopes that Lange "will embrace" the opportunity to return to radio and remain with the team.
"Once FSN informed us of their decision, we told them we'd like to offer Mike the radio job and keep him in the broadcast family," Penguins vice president of communications Tom McMillan said.
