Nick Rewind appears to have started with two DVDs in its original Nickelodeon Rewind collection, with the first two released on May 17, 2005. Later, the Nick Rewind branding also included digital “volumes” and season releases, so the total depends on whether you mean the original DVDs only or the broader digital catalog.

What that means

  • Original DVD collection: 2 titles at launch.
  • Broader Nick Rewind releases: more than 2, because the catalog expanded into downloadable volumes and other releases.

If you mean the physical DVD count only , the safest answer from the available info is 2 at the start.
