News programs (e.g. television news programs) and news stories (e.g., on-line news) are acquired and the system enables the user to easily move among and randomly access the segments of news programs and quickly locate the segments of a particular subject. News stories related to the segment of news program being viewed can be identified and displayed. Flexible playback allows speeding-up the display of the news program while displaying summary of one or more program segments and accelerating playback of a paused program after resuming from the pause. The system can additionally indicate to the user which news story is currently being viewed, and which news stories have already been viewed. ## Claims ### Claim 1 A method for reviewing multiple television programs, wherein at least one of the multiple television programs is received in real time, the method comprising: displaying one of the multiple television programs to a user by a first display device;
