This needs some cleanup; a lot of the examples are Next Sunday AD. The description could also use a rewrite, it's a bit confusing as it is and doesn't explain the trope very well.

Would "The Future of Us" by Jay Asher and Carolyn Macker be an example of this? To those who don't know, it takes place in 1996 and is about two teenagers who get hold of an AOL demo CD that somehow allows them to access their Facebook profiles from fifteen years in the future.

And it seems all of this is only because the author wants the story to become real life.

Concerning Harry Potter: I seem to recall reading an interview with Rowling where she states most of the events of the books take place during the 1990s. This would make the epilogue of the final book actually the only scene taking place more or less during the time of publishing.

DN 3 D wasn't released in 1997. It was actually released in early 96.
