Rainmaker Entertainment, Inc. (formerly Mainframe Entertainment) is a UsefulNotes/{{Vancouver}}-based computer animation studio, specifying mostly in animated TV shows and DirectToVideo movies.

Established by Gavin Blair and Ian Pearson, both English born, the company was founded with the intent of creating the first computer animated show, ''WesternAnimation/ReBoot''. Prior to that, the two were known mostly for providing the computer animation for the rock band Music/DireStraits music video "Money For Nothing." (If you look closely, one of the fictional videos is credited to the "Ian Pearson Band".)

The production of ''[=ReBoot=]'' was troublesome because the amount of money going into a project like this required an entire animation studio to be built. This meant that they needed to start with a full season or nothing. Unlike other animated shows where they produce a concept pilot to try and sell the series, the money for equipment and business space was much higher.

When ''[=ReBoot=]'' became a hit, Mainframe became a hot item to produce MerchandiseDriven series, most notably reviving the struggling Franchise/{{Transformers}} brand with ''WesternAnimation/BeastWars''. ''Beast Wars'' was an even bigger hit because it came with a built-in fanbase. The story quality, voice acting, and CGI were all top notch.

The animation of their early seasons appear to be primitive, especially considering Creator/{{Pixar}}'s groundbreaking work for ''WesternAnimation/ToyStory'' at the same time. But it should be considered that they were still the first people to get it [[UrExample out in the open]].

''[=ReBoot=]'' remained their favorite baby and they rejoiced when they were able to [[UnCanceled continue]] the series in 2001. When the show ended again, this time it seemed for good because Gavin Blair and Ian Pearson left the company to pursue other projects.

Unfortunately, this was also one of the turning points when the company began to fall into trouble. The MerchandiseDriven shows fell into less competent hands and were not nearly as popular as ''Beast Wars''. They barely managed to stay afloat with Direct-To-Video franchises like the Barbie series, but it fell apart. In 2007, the company was bought out by the Rainmaker Income Fund and renamed Rainmaker Entertainment. They kept the Mainframe studio to use for entirely animated productions, while Rainmaker itself is known for doing special effects for LiveActionTV, until being bought by Creator/CompositeImageSystems and later Creator/MethodStudios.

Today, Rainmaker Entertainment consists of Mainframe Studios, which focuses on CGI-animated television series, and Rainmaker Studios, which develops feature-length animated films. As of October 2016, [[http://www.rainmaker.com/?/site/news/92 Rainmaker Entertainment has folded under WOW! Unlimited Media]], a new holding company formed after Rainmaker purchased the New York-based [[Creator/FrederatorStudios Frederator Networks]].

!! Tropes:
* ArtEvolution: The progress of computer graphics took great effect on their later productions.
* ConspicuousCG: All of their early shows, owing to the primitive nature of 3D computer animation at the time.
* CutShort: Post-''WesternAnimation/BeastWars'', a LOT of Mainframe's serialized shows tend to [[LeftHanging end with no resolution]], [[DownerEnding or]] [[{{Cliffhanger}} worse]].
* InNameOnly: The Mainframe Studios division launched in 2013, which is Rainmaker's television unit.
* NoFlowInCGI
* SpiritualSuccessor: Nerd Corps Entertainment is considered this. ''WesternAnimation/StormHawks'' isn't produced by Mainframe, but has some of the same talent working on it. Sadly, they were absorbed by Creator/DHXMedia in 2014.
