Platform	Status	Information
Amiga 1000/2000	1988-93: Lost; defunct 1993-99: Found; defunct	Internally referred to as EPG Esquire. Early versions (1988-93) seem to be based off EPG Sr., however omits the crawl ads and title, instead providing a blank space above with IFF graphics, text-only, and genlocked video for advertisements and programs, with later versions (1993-99) include similar features, however also introduced a grid that showed the current listings and the next two timeslots for each channel simultaneously, referred to as New Look. As of November 7, 2020, while the early versions are still lost (and is most likely never to be found, as when Prevue software was updated, previous versions were overwritten.) Various versions of the New Look have been found, along with special LaserDisc-based versions.
Windows NT	Junior: Partially found; active Hollywood: Lost; active	Prevue Junior: Separate version based upon Esquire New Look, which was first introduced in 1997. This version was presented in a very limited fashion, with listings alternating by individual pages instead of scrolling and showing just program information on the top portion of screen (though some versions offered genlocked video and graphical ads. Hollywood: Current version of the Prevue Channel software, then referred to as TV Guide Channel after an acquisition. This version switched to the Windows NT platform similar to Prevue Junior, and offered different styles throughout different years, starting with a tan guide reminiscent of Motorola cable boxes of the time. While both versions seem to still be used in little cable markets, however only the Prevue Junior software seems to have been found, however hasn't been released most likely due to legal reasons.
Sneak Prevue
Platform	Status	Information
Amiga 2000	Found; defunct	Separate from other versions of Prevue, as this was made for pay-per-view barker channels. The channel relied on LaserDiscs, which were controlled by the Amiga. While the software has been found, it is currently not usable in emulation, as the proper expansion card is currently not emulated, and as such results in a Guru Meditiation.
Windows NT	Partially found; defunct	A version of the Sneak Prevue software ported to Windows. This was most likely produced during a time when there were various different projects to port Prevue to Windows. It most likely operated in the same way as the Amiga software. While the software has been found, it's currently not available for download, most likely the same reason as the Prevue Junior software.
