The "Dancing Baby," also called "Baby Cha-Cha," is a 3D-rendered animation of a baby dancing. It quickly became a media phenomenon, internet meme, and one of the first viral videos, in the late 1990s.
History of the Dancing Baby Animation 
The "Dancing Baby" phenomenon refers to a 3D rendered animation of a baby performing a cha-cha type dance. It originated as a collection of experimental testing data and files, ultimately released in Autumn of 1996 as a product sample source file (sk_baby.max) with the 3D character animation software product "Character Studio", used with 3D Studio Max (both products from Kinetix/Autodesk). The original sample source file was produced and prepared by the original Character Studio development team (Michael Girard, Susan Amkraut, John Chadwick, Paul Bloemink, John Hutchinson, Adam Felt) at Unreal Pictures and Kinetix/Autodesk, amongst several other sample files. The cha-cha animation was created using the "Biped" animation system of Character Studio by Robert Lurye and Michael Girard. The 3D model of a human baby was added later by the development team as one of the character "skins" for the rendered animation. The original "Toddler with Diaper" model #VP5653 was built by, and courtesy of, Viewpoint Datalabs, with the bulk of the skinning and rigging performed by John Chadwick using the "Physique" skin/deformation system in Character Studio, and final edits by John and members of the Autodesk development team. After the first pre-release application of the 3D baby model to the cha-cha animation (and from pre-release showings), Kinetix/Autodesk employees realized it was amusing to see a baby dance a cha-cha rather than just walk, this helped ensure the selection of the 'dancing baby' as a sample file for debut release of Character Studio and for demonstration videos in product promotion.
The animation of the original dancing baby data consists of heavily researched and adapted physics models to automate animation along with interpolated manually animated keyframes that are generated and synthesized by the "Biped" system of the Character Studio product. Contrary to popular misconceptions, none of the original Dancing Baby animation data were created using motion capture.
After the 3D source file was released to public with the Character Studio product (Autumn 1996) users and animators were able to render their own video clips of the 'original' animated dancing baby (sk_baby.max) and circulate these via the Compuserve (internet) forums, World Wide Web (commercial and private web sites), and in print ads and unrestricted e-mail. Such activity proliferated most significantly from mainstream (Windows users) royalty-free access to and user renderings of the 3D dancing baby source file for use on internet and in broadcast television via several news editorials, advertisements, and even comic programming in local, national (U.S), and various international markets.
Dancing Baby animation clips using the sk_baby.max file originally appeared on numerous web sites, and then proceeded to show up in a broad array of mainstream media, including television dramas (e.g. Ally McBeal), commercial advertisements, and music videos between 1996–1998.
Later, several interesting variations to the original animation were also produced by modifying the sk_baby.max sample file's animation and the baby model itself with noticeable changes, and some not even dancing at all. Many users/animators were responsible for improved, diverse, and even more amusing variations of the dancing baby animation and character model itself. However, evidentially the most widespread broadcasting, distribution and viewing of 'the' Dancing Baby animation that became so popular consist of lighted and rendered views of the original and/or virtually unmodified sk_baby.max model and animation. As a result, variations of the dancing baby animation did not become quite as popular or as influential as the original sk_baby.max animation and source file. This is evident by observing the references to most popular uses of Dancing Baby during the primary wave of its proliferation 1996-1997 and comparing those animations to the original sk_baby.max character mesh and animation to note they are virtually unchanged if at all. Some exceptional variations have followed, but cannot be credited for the original internet phenomenon and proliferation. Such stylized versions and parodies included a "drunken baby," a "rasta baby," a "samurai baby," and others, but none of these became as popular on the Internet as the original file, which still remains in active circulation, and has been adapted to various musical soundtracks.
Appearances in mainstream media 
The Dancing Baby animation spread quickly on popular web forums, individual web sites, international e-mail, demo videos, commercials, and eventually mainstream television. Awareness of the meme most significantly increased when featured on CBS, CNN, and on Fox's Ally McBeal comic drama series. The same animation was shown on several episodes of Ally McBeal as a recurring hallucination, suggesting a metaphor for the ticking of Ally's biological clock - further enhancing it as a 'meme'. On that show it was curiously accompanied by a Vonda Shepard cover of the song "Hooked on a Feeling." Various commercial advertisements presented the Dancing Baby animation to international markets continuing the mainstream media attention. This particular manifestation of the video, bound to the song, is widely distributed and referred to as the Ugachaka (or Oogachaka) Baby.
More examples of the Dancing Baby used in mainstream media are below.
