How workable would a weeklong boycott of Hulu be?

OK, so much like GoDaddy, Hulu is an internet-based business. They make most of their money off of ad revenue, I believe.

My question is, 1) how easily could we organize a boycott (for, say, a week) of Hulu through Reddit, Facebook and other such things? 2) How effective would it be?

EDIT: Or perhaps a boycott of Fox Corp. in general.
