Courtney began working in professional sports when he was 14, starting as a public relations assistant for the Kings in 1971. Under the guidance of announcer John Ramsay, and by doing games for his Beverly Hills High School varsity football and basketball teams, he learned the job well enough to become Ramsay's backup for both the Kings and the Lakers.
In 1978, he moved to Houston as public relations director of the Houston Aeros in the World Hockey Association. When the team folded a year later, he began a career in radio and television and found himself in demand as an announcer.
When he wasn't at an arena or a ballpark, Courtney did traffic and sports updates for three Los Angeles area radio stations.
His announcing jobs led to voice roles in the movies "Tooth Fairy," ''Angels in the Outfield," ''61(asterisk)" and the TV show "Home Improvement."
Courtney is survived by wife Janet.
