Abstract
An interactive broadcast may include television programming and associated services such as closed caption scripts. The audio portion of the broadcast television programming, in closed caption script format, is parsed and compared to a key word database which may be preprogrammed by the user. The closed caption text may be displayed in real time. When a match is identified, an event is fired. The particular event which occurs and the key word may be programmed by the user.
