The 1967 National Hockey League (NHL) expansion saw the start of six new teams. It doubled the size of the NHL. One of the new teams, the San Francisco Seals, came out of the Western Hockey League but were renamed the California Seals when they joined the NHL. They were then known successively as the Oakland Seals, Bay Area Seals (for two months), before settling on the California Golden Seals. In 1976, the team moved to Cleveland and became known as the Barons.
