::: Currently Reading: Killing Time, Della Van Hise. In this 1985 novel never ripped off by anyone or anything, time-travelling Romulan idiots ...
In fact, because it's a time-travel plot, stories written before 1985 were able to rip it off! In TOS that would be "City on the Edge of Forever," but not "All Our Yesterdays," "Assignment: Earth," "Tomorrow Is Yesterday" or "Star Trek IV."
Subsequently, every twentieth TNG and DS9 ep, every tenth VGR, and every other ENT, would use the plot. And for Doctor Who -- well, it's impossible to tell if the Whoniverse is supposed to have a consistent timeline anyway, and if the Doctor doesn't care, why should we?
See also Back to the Future, Bill and Ted, their respective cartoons, Futurama, Warehouse 13 (which did it by mental transfer, like a Lovecraftian Yith) and Eureka (where the changes affected the entire season).
