In his youth, Bjørnsen was a promising speed skater. He was junior Norwegian champion in 1951. He worked for the Norwegian Broadcasting Corporation between 1961 and 1991, and was NRK's main commentator for speed skating most of those years, together with fellow NRK veteran journalist Per Jorsett. He also hosted the popular Norwegian Broadcasting Corporation game show Kvitt eller dobbelt ("Double or Nothing") for many years. In 1991, Bjørnsen left the Norwegian Broadcasting Corporation, and began working for cable channel TV3, where he hosted the game show Lykkehjulet (a Norwegian adaptation of Wheel of Fortune).
In April 2008, Bjørnsen was diagnosed with terminal pancreatic cancer, and he died from the illness seven months later, on 14 November 2008.
