Some of the writers among us may remember Amazon having a sitcom opportunity. I assume the pilots they've filmed and are showing (via LoveFilm) are from this original opportunity (I have no proof).
All eight comedy pilots are here and available until the 19th (though why this is is irritating -- can't they just leave them up there for all to view?) http://www.lovefilm.com/c/?m=d&token=%253Fu%253D%25252Fcatalog%25252Fvideo%25253Ff%25253Dcollection_id%2525257C10607%2526m%253DGET
