Have you tried Amazon’s streaming service yet? The online retailer has added 2,000 more titles to their service, which is offered free to Prime subscribers. New content includes the entire Star Trek television franchise (Deep Space Nine, Voyager, Enterprise, and Next Generation), episodes of Numb3rs, Medium, Cheers, and Frasier. For those of you watching on larger displays, many of the titles are fortunately offered in HD. You can try Amazon Prime for free for one month, which includes free unlimited 2-day shipping on purchases.
UPDATE: It seems Amazon Prime may not include the “entire Star Trek franchise” as stated in their promotional graphic.
A message now appears when trying to view Star Trek Original Series Seasons 1, 2 and 3: “Due to our licensing agreements this video is currently not available for purchase or rental.”
