Two different actresses played Alexis Carrington: Nicollette Sheridan of “Desperate Housewives” fame and Elaine Hendrix.
This series got very low ratings on the CW but survived (as did many others) because of revenues the studios received from international licensing deals and Netflix. The CW is 50/50 owned by CBS Entertainment Group (now part of Paramount Global) and Warner Bros. Entertainment (now part of Warner Bros. Discovery).
But the studios ended the lucrative Netflix deal in 2019 to help lift their new streaming services HBO Max and Paramount+. International deals dried up as well because both studios are trying to keep their content in house, according to Hollywood Reporter.
Losing those two revenue sources made “Dynasty” unprofitable, the story noted.
Both studios are trying to now sell the CW.
