• TV program activity of the user collected in the first viewing activity collection,
• use the second viewing activity collection to provide second VOD program
• recommendations to the user via the VOD program recommendation service,
• collect TV program viewing activities of the other users to produce a third
• viewing activity collection, and
• create one or more clusters of users based on the first viewing activity collection
• and the third viewing activity collection,
• wherein, when using the first viewing activity collection to make
• VOD program recommendations to other users, the one or more processing units are further
• configured to:
• make the VOD program recommendations to the other users based on the created one or more clusters, and
• wherein the one or more processing units are further configured to:
• delete the user from the one or more clusters responsive to receiving the indication that the user wishes to turn on the VOD program recommendation service.

• one or more instructions to create one or more first clusters of users based on the first viewing activity collection and TV program viewing activities of other users;
• one or more instructions for using the first viewing activity collection to make TV program recommendations to the other users via a TV program recommendation service;
• one or more instructions for determining whether an indication that the user wishes to turn on the TV program recommendation service has been received;
• one or more instructions for deleting the first viewing activity collection responsive to receiving the indication that the user wishes to turn on the TV program recommendation service, wherein deleting the first viewing activity collection includes deleting all of the TV program viewing activity of the user collected in the first viewing activity collection;
• one or more instructions for collecting TV program viewing activity of the user, that occurs subsequent to the received indication and the deletion of the first viewing activity collection, to produce a second viewing activity collection, wherein the second viewing activity collection includes none of the collected TV program viewing activity of the user from the first viewing activity collection;
• and

• creating, by the one or more computing devices, one or more second clusters of users based on the third viewing activity collection;
• and
• using, by the one or more computing devices, the third viewing activity collection to provide second TV program recommendations to the user via the TV program recommendation service.
