The fuse under TV

More evidence of exploding broadcast:
: 1 million videos sold (read: revenue) on iTunes in just 19 days.
: 4 million podcast subscriptions (read: loyal audience) for NPR.
: As soon as iTunes promotes video, popular podcast Diggnation gets more audience on video than audio (read: demand).

: CORRECTION: On NPR, that is indeed 4 million downloads, not subscriptions. I linked to the Live Remote post, which said subs. Paid Content said downloads. (Thanks to John Davidson in the comments for the correx.)
