> I know almost no one who pays for TV a la carte through iTunes or Amazon.
You now know of me. I spend around $50/month downloading content from Amazon, be it music or tv. I would buy Game of Thrones as it came out if I could, but I can't.
Absence of evidence isn't the evidence of absence. Especially if you've done no investigation.
>I am skeptical they'd pay even if it was available for $4.99 an episode.
$5 might be a bit steep for some, $2-3 is just about perfect. But honestly I'd still pay $5 for content created at this level, if not just to encourage the people creating this quality of content to keep doing it.
Your skepticism is powered by your lack of knowledge and research. Do the work, then come back and comment.
