Hopefully I can explain this clearly. Anything that is set in the future, but one that we've already lived through, and where the fiction didn't match our eventual reality. For example, the future of Back to the Future Part II takes places in 2015 but there are many things in that movie that obviously don't exist yet.
Basically, anything depicting a future "through 2015" that is now extremely dated, still not possible or hasn't happened yet.
