* The Energizer Bunny has gone though a fair bit of this. Compare the [[http://www.youtube.com/watch?v=qiFQsxGUQOI original animatronic]] by [[Film/ShortCircuit Johnny 5]] creators [[http://allfx.com/ All Effects]], to [[http://www.youtube.com/watch?v=V_bjEB2C2nU this commercial]] with one by Creator/IndustrialLightAndMagic.
** As of 2016, the Bunny's gotten a [[https://www.youtube.com/watch?v=pJAjb2GYHIM complete makeover]] with a lighter fur color and more expressive movement.
* The early toy commercials for TransformersGenerationOne had early models for several characters, especially between them and the show. [[http://tfwiki.net/w2/images2/6/66/Jetfireg1commercial.jpg Jetfire's the most obvious]] [[http://tfwiki.net/w2/images2/2/26/Jetfireskyfire.jpg in this regard]].
* CGI and Flash character [[Music/{{Schnuffel}} Snuggle Bunny]] (Schnuffel in German) created by German music company Jamster. [[https://www.youtube.com/watch?v=ps9e1vqOKtM Started out fuzzy looking in the music videos "Snuggle Song"]] and [[https://www.youtube.com/watch?v=SGF8dhihicU "I love you so"]] until the music video [[https://www.youtube.com/watch?v=6AyXc7s8l3A "Doo Bee Doo Bee Doo"]] where Schnuffel looked less fuzzy and more smooth looking. The character later shifted from CGI to Flash animation starting in the music video "Without You" which stars his girlfriend Snuggelina.
* The mascot of "Chewits" sweets manufactured in Britain since the 1960s, Chewie the Chewitsaurus, has suffered from this for years. The original claymation advertisements featured him as the 'Monster Muncher' which was consistent until the switch to 2D-animation in the 90s/2000s. [[https://www.youtube.com/watch?v=A_AceNz7HAc He was more popular than ever during this period]]. But then what followed were constant art style changes, averaging every 3-4 years. [[https://upload.wikimedia.org/wikipedia/en/8/83/Chewie_the_Chewitsaurus.png As of 2016 "Chewie" is a far cry]] from his former smiling [[NotZilla Godzilla-resembling]] self.
