One of my billionaire fantasies was to one day archive all of TV Guide and then use that to line up airing blocks for each decade at the start of every decade and then have it available as a streaming option.

When/if you get around to it I'm basically already in the process of doing this (although just for the fascinating dataset of knowing all the movies that played on television in the 90s, when, and how often). TV guide is tough. The New York Times has the TimesMachine though and those have very comprehensive television listings. Possibly as comprehensive as the TV Guide which I was surprised by.
