In this case, it does. The online streaming part of the Olympics (at least the part we are discussing) is something the ISP has to 'opt in' for and pay for. Bresnan had registered for this feature then removed it so Bresnan customers no longer have access to the online Olympic coverage. ESPN360.com is another site that uses a similar access type where the ISP has to opt in to it for their customers to use it.
BTW the entrance to the site in question for the Olympics coverage is here: »www.nbcolympics.com/entitlement/ ··· der.html
As you can see Bresnan is no longer on the list of providers when they used to be a few days ago.
