-The American Archive of Public Broadcasting, a collection of PBS programming spanning back into the pre-PBS NET days
-The 88x31 Gif Collection, exactly what it says on the tin
-Historical Channel List Archive, an archive of primarily 90s and 2000s tv channel listings
-Windows Media Player Skins Archive, archive of wmp skins (also provides downloads for each skin!)
-Windows XP Tour, ok this isn't really a collection/archive like the rest of this stuff BUT it is a relatively faithful of the Windows XP Tour that i think is pretty neat
-Matt's TV Guide Page, a bunch of old tv guide listing going all the way back to the 40s, taken from tvguide magazine!
