I honestly don't know. It might also include people that get Prime for free (new moms, college students, etc.), who also don't get streaming video. Assuming that the 5M figure is correct, and that it includes everyone with access to Prime shipping, it might be as little as 1M or less who qualify for the free streaming, although my gut tells me it's probably a lot more than that. All that being said, I don't think it's all that important. I wasn't trying to imply that 5M current Prime members compare to 24M Netflix streaming customers; I was trying to say that they have a really big foot in the door, which they could use to rapidly leverage their way into the market. The more important number are the 120M+ customers. Amazon can pitch them with, "You didn't want Prime for shipping, but maybe you'd like it for videos! (Especially if you're dissatisfied with Netflix!)" There are also rumors that they will soon let Prime members "rent" eBooks on their kindles for free (with a limit on the number of titles they can have at any given time). That would pull more people into Prime, and some of those people would inevitably take advantage of the free streaming.
