Abstract
While reviewing potential programs when using an interactive programming guide, a viewer can select to place information regarding specific programs in a list (in one embodiment, such entries are made on an automated basis). The viewer can then recall that list to make a final selection of a present program to view (or record). In some embodiments, this list can be automatically cleared in response to a predetermined trigger event.
