The arena's first tenants were the California Seals of the Western Hockey League, who moved across the bay from the Cow Palace in 1966. The owners of the San Francisco Seals had been awarded an expansion franchise in the National Hockey League, on the condition they move out of the Cow Palace and into the then-new Oakland Coliseum Arena. The team changed its operating name from San Francisco Seals to California Seals in order to draw fans from both San Francisco and Oakland. The California Golden Seals continued to play at the arena after having transferred to the NHL, until the team moved to Cleveland after the 1975–76 NHL season.
