In September 2004, launched a group dedicated to Crossovers, which has archived more than 700 stories as of April 2013.

Throughout the 1990s, works of crossover fiction were discussed on alt.startrek, alt.tv.dawsons-creek and alt.tv.x-files among many others. Another sci-fi crossover archive was established in 1997, but has also since been removed. īy April 1995, a .fandom poster known by the handle Krikket began compiling an archive of crossover science fiction stories posted online, but it no longer exists. This zine work bled into Usenet groups, where crossover work was discussed as early as October 1994. The trope became incredibly popular in zines throughout the 1980s, with no constraints on the fandoms that would mix together. Fandoms have used crossovers in their fiction since as early as 1979 when a story featuring characters from Star Trek and The Man from U.N.C.L.E. Crossovers that are either artist-sanctioned or unofficial have continued to be found in mass media, including works of literature, movies, comics, television series and video games.
