S.C.I.F.I. World was a daytime programming schedule for the Sci Fi Channel that started on July 17, 2000 and ended on December 21, 2001. It was what replaced varied programming in favor for mini-marathons.
Divided into five different segments in accordance with the days of the week, each day centred on a particular science fiction theme, which the marathons followed, airing from 10 AM to 4 PM. These themes were named in such a way that, when assembled, they formed an acronym of the channel's name.
To reinforce this novelty, the programming schedule was advertised by way of animations depicting it as a theme-park which various science-fiction characters such as James T. Kirk, Duncan MacLeod, and RoboCop inhabited. Aside from this, graphic teasers, trivia, and on-air questions were aired to amuse and inform the viewer and promote the SciFi.com website.
Despite criticisms made by viewers in favour of reverting to a more varied programming schedule, this format of airing marathons five times a week continues to this very day although, since then, S.C.I.F.I. World has ceased to be as is much of Sci Fi Channel's second-run programming.
