Audrey Meadows was the only cast member to receive residual payments for the show for her entire life. This was a result of her shrewd manager, who predicted the prospect of a "rerun" even in the early stages of television, before precedent was set for it. As a part of her contract, she was told to stipulate that if the show were to air in subsequent time slots in the future, she would be paid royalties, which is an interesting bit of history, because it's now a standard condition for all television work that the involved parties from an episode should get paid for each showing of it. These days it applies to directors, actors, actresses, writers, and voice actors, along with others in different capacities as well.
