This entry is trivia, which is cool and all, but not a trope. On a work, it goes on the Trivia tab.

What does God of War have to do with Total Recall?note 

Lark: Alright! Pre-ordered my order of Final Fantasy Type-0!
Summer: First of all, don't pre-order. Second, since when did you want that game?
Lark: I don't. But it comes with a demo of Final Fantasy XV.
Summer: Are you serious? You're going to pay sixty dollars for a three-hour demo?
Lark: Well, I already paid thirty dollars for an one-hour demo when I purchased Ground Zeroes.
Summer: That's true.

Basically this is when a work sells itself on including a preview for a much more anticipated work. This is often done with second string titles that would fizzle out on their own. This has become less prevalent (or at least less successful) with the rise of easier video sharing and video game demos on the Internet, but still there are some fandoms dedicated enough to shell out cash for a ticket to Movie You Might Have Ignored Completely if it means they get a chance to see just an ad for Everything You Ever Liked: The Movie.

This is also done on TV shows. You get a trailer (more often called a "sneak peek") packed somewhere in the commercials (although usually at the end) for an anticipated blockbuster.

The inverse is standard procedure, where an anticipated work includes a preview for a less-hyped title, in the hope that attention will rub off on it.

Examples:

Film

Literature
  • The Warrior Cats and Seeker Bears book often have preview pages for the next book, being written by the same author. In fact, one of the main selling points of the summer 2012 release Enter The Clans note  is that it contains a teaser for Survivors, the new (not really) Erin Hunter series, and the fifth Super Edition, Yellowfang's Secret.
  • The Tolkien Reader was originally conceived by publishers as a way of broadening interest in Tokien's non-fiction essays by mixing abridged versions of them with some of his shorter fiction.
  • In fact, this is extremely common with books; often the paperback release of a book will contain a preview of the sequel or another book by the same author as a way of building hype for the upcoming book (and possibly in the hopes of getting people who bought the hardcover to buy the paperback as well).

Live-Action TV

Music
  • One Direction's first North American gig was as an opening act for Big Time Rush. Although they had a hit TV show, the real-life BTR didn't really have a huge following. Meanwhile, 1D was rapidly starting to gain momentum across the world through social media. Not only did many fans buy the tickets only for One Direction, actually leave the arena after they finished playing, leaving BTR performing to arenas that were more than half empty.
