This may be old news for some, but I just happened across a trailer on YouTube announcing that Marvel Comic's home website is hosting episodes of the 1978 Spider-Man series.

Marvel is supposed to release one new episode per week - on Thursdays, I believe.
Now if they would only offer the entire series on R1 DVD, it sure would be sweet. (I know, I know... but a guy can dream, can't he??)
Anyhow... here's a link to the site's episode listings:
