Systems and methods identify broadcast transmissions of interest to a user by comparing a user's interest profile to characteristics, such as topic phrases, associated with available broadcast transmissions. The method comprises receiving from a viewing station via a communication network an interest profile associated with a user. The interest profile includes data representing a plurality of topics of interest to the user that relate to broadcast transmissions. After receiving the interest profile, a text-based search is performed to identify available broadcast transmissions that match at least one topic of interest included in the interest profile, and a list of one or more of the available broadcast transmissions that match at least one topic of interest included in the interest profile are transmitted to the viewing station so that one or more of the available broadcast transmissions can be selected from the list and presented via the viewing station.
