Original net animation
An original net animation is an anime that is directly released onto the Internet. This format mirrors the term original video animation, which has been used in the anime industry for straight-to-video animation since the early 1980s. Some ONAs may also have been aired on television if they were first directly released on the Internet. Most animation in Japan is made for television or other audio-visual formats, including ONAs viewable on mobile devices or computers. A growing number of trailers and preview episodes of new anime are now released as ONA content. For example, the anime movie of Megumi can be considered an ONA.
Makoto Shinkai was a pioneer of original net animation in the late 1990s. He produced his first animated short films on a home computer and distributed them on the Internet. His earliest work included Tōi Sekai (Other Worlds) in 1997. He followed this with Kakomareta Sekai (The World Be Enclosed) in 1998. Another notable early short was Kanojo to Kanojo no Neko (She and Her Cat) in 1999. These projects established a foundation for independent creators to reach audiences without traditional studio backing. The technical limitations of home computers shaped the visual style of these early experiments.
As broadband Internet bandwidth began to increase in speed and availability, delivering high-quality online video over the Internet became a reality. In the early 2000s, the Japanese anime industry began broadcasting ONA web series on the Internet. Early examples of ONA series include Infinite Ryvius: Illusion from 2000. Ajimu appeared in 2001 alongside Mahou Yuugi that same year. Increased connectivity allowed producers to move beyond simple animations into more complex narratives. This shift marked a turning point where internet distribution could support full production values previously reserved for television or film releases.
ONAs have the tendency to be shorter than traditional anime titles, sometimes running only a few minutes. There are many examples of an original net animation such as Hetalia: Axis Powers which last only a few minutes per episode. But while that was true for the beginning of the 2010s, this began to change in the second half of the decade. Full series began to emerge with lengths comparable to standard broadcast shows. The format expanded from brief clips into substantial serialized content designed for digital consumption.
Full series began to be licensed exclusively for streaming services like Netflix, Amazon Prime Video, and Disney+ during the latter part of the 2010s. These platforms started acquiring rights to distribute original net animations directly to global audiences. The partnership model shifted how creators approached production and audience reach. Traditional broadcasters no longer held exclusive control over new anime releases. Digital services became primary venues for launching new animated properties worldwide.
