[2] Baldwin became one of the youngest executives in professional sports when he became a founder and partner of the WHA's Boston-based New England Whalers in 1971 at the age of 28.
The Whalers first season in the WHA was a success both on and off the ice with coach Jack Kelley's team winning the 1973 AVCO World Cup Championship.
Baldwin served as the managing general partner of the Whalers until the team was sold to local ownership in 1988.
In August 2010, Whalers Sports and Entertainment was hired by the NHL's New York Rangers to manage the day-to-day business and marketing affairs for their AHL affiliate the Hartford Wolf Pack.
[5][6] Baldwin licensed the name Connecticut Whale to a franchise of the Premier Hockey Federation, a founding member of the 2015 upstart league.
When Belzberg left the ownership group, Baldwin recruited Roger Marino, a Boston investor.
[10] The Baldwins produced such films as Mystery, Alaska, Odd Man Rush, Sudden Death, From the Hip, Spellbinder, and Joshua, among others.
