Rosinski began his broadcasting career at UPI, where he was a reporter and sports director for UPI Radio. He first began working for Westwood One in 1985 after spending three years at UPI Radio, and stayed there until 1992. Rosinski's primary responsibilities were to cover football and college basketball games for the network.
Rosinski left Westwood One for a job as the Atlanta Falcons' radio play-by-play voice on WSB-AM, a position he held until the end of the 1994 season when he took the same position with the expansion Carolina Panthers. He was with the Panthers until the end of the 2004 season and called every major game for the franchise that occurred while he was there, including two NFC championship game appearances and Super Bowl XXXVIII. Rosinski wrote a book about his career with the Panthers, appropriately titled Bill Rosinki's Tales from the Carolina Panthers, which was released in 2007.
After a year layoff Rosinski returned to Westwood One to replace Dave Sims, who became the voice of Sunday Night Football, as one of the network's Sunday afternoon play-by-play men alongside Harry Kalas. Rosinski was paired with former NFL coach Dan Reeves for all three of his seasons at Westwood One and called playoff games for the last two of those seasons including the 2007 NFC Championship game. Rosinski returned to the college basketball ranks for Westwood One in 2009, calling early round regional games for the network in what proved to be his last assignment for Westwood One.
