INMU began around 2001, when some particularly terrible gay porn videos from COAT Corporation were found to include a rising baseball star in Japan. Eventually, gossip on 2ch reached the mainstream, and the baseball player was so humiliated that he had to join a team in America afterwords. INMU comes from 真夏の夜の淫夢, or "A Midsummer's Night's Lewd Dream," the name of the most famous video.

It remained a relatively low-key fad afterwards, until the Touhou fan work Cookie came along in 2010. Since both were low quality works that triggered people easily, parody videos of Cookie began to include elements from INMU to troll viewers, such as 音MAD switching from Cookie sources to INMU sources halfway. Eventually, INMU acquired its own reputation as a video source, and sort-of succeeded Gachimuchi as the obscene video fad of Niconico. Unlike Gachimuchi, INMU really only known in Japan, while Gachimuchi is pretty well known to netizens in Korea, China, and a little bit in the West.

INMU is also funnier because there is much more to work with, it has a lot of history behind it, and it is probably more accessible to Japanese video creators than Gachimuchi.

The picture is a Touhou/INMU doujinshi, which references the Cookie project. Its a pretty interesting read.
