Something I've been thinking about for a while is the impact speedrunning can have on a game's overall popularity and whether or not game developers have intentionally added, or refused to fix bugs in particular titles with the hopes that speedrunners would exploit them, more people would run the game, and the game would become more popular and potentially bring in a lot more revenue.

Are there any notable examples of this happening in the past? If so, how successful have these efforts been and how would something like this impact the speedrunning scene in the future?
