The cancellation of 'NCIS: Red' was a missed opportunity for CBS, but it's not the only spin-off that never made it to air. The network's selective approach to spin-offs has been a defining feature of the 'NCIS' franchise's expansion. While 'NCIS: Red' never materialized, the franchise has continued to grow with other spin-offs, such as 'NCIS: New Orleans', 'NCIS: Hawai'i', 'NCIS: Sydney', 'NCIS: Origins', and 'NCIS: Tony & Ziva'. The failure of 'NCIS: Red' was hardly a sign of the franchise's decline, as the series was never given a full order from CBS. The network's selective approach to spin-offs has allowed it to maintain the integrity of the 'NCIS' brand while still expanding its universe. The franchise has continued to evolve, with new spin-offs and a sixth spin-off on the way. The next 'NCIS' TV series is slated to premiere later in 2026, and the network has remained selective about which spin-offs it develops. This approach has allowed CBS to protect the franchise and maintain its popularity, even as it continues to expand its universe.
