But soon, some fans will have to wait eight days to see Fox content online at Hulu or on Fox.com. Rather than throwing their already-aired content up on the Web for everyone to see immediately, the company said that it will require a username and password to prove that an online viewer has a paid subscription to see the content, i.e. a cable, satellite or Hulu Plus subscription.

And right now, the report said, Dish Network is the only cable service that’s signed on to the deal. The lockdown goes into effect Aug. 15.

The idea of authentication, of course, is not a new one, as The Los Angeles Times highlighted, as the television industry tries to stem the tide of “cord-cutters” taking away revenue from cable.
