Preview Piggybacking

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

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.

Live-Action TV

Video Games

Western Animation
  • On the day of May 28, 2011, many bronies went to their TV sets and watched Garfield: The Movie just to see the Equestria Girls commercial.
  • Done In-Universe and made fun of in South Park episode "The New Terrance and Phillip Movie Trailer". The boys were attempting to watch through Russell Crowe: Fightin' Around the World, a show which none of them cared about and had others around them give deriding comments about, just so they can see a commercial preview of Terrance and Philip: Asses of Fire 2.
