I don’t know much about marketing, let alone about marketing decades old television shows, but it would surprise me if doing the work to stream all of that were economically viable, let alone more economically viable than other things HBO could work on instead. Ten or twenty “best of” episodes (with “best of” decided by both content, licensing, and the quality of available recordings) might be economically viable, but thousands of episodes?
