providing the piece concurrently with the primary content data.

5. The method of claim 4, wherein identifying a portion of the subsidiary data comprises accessing a database which stores a plurality of portions of the subsidiary data.

6. The method of claim 1, wherein the primary content data comprises data of a television broadcast.

7. The method of claim 1, wherein the primary content data comprises data of a digital satellite broadcast.

8. The method of claim 1, wherein the primary content data comprises data of an Internet broadcast.

9. The method of claim 1, wherein the primary content data comprises data of an audio-only broadcast.

19. The method of claim 1, wherein determining whether subsidiary data exists comprises accessing the electronic program guide using the determined time and channel.

20. The method of claim 1, wherein obtaining the subsidiary data comprises retrieving the subsidiary data from a memory of the entertainment system.

21. The method of claim 1, wherein obtaining the subsidiary data comprises retrieving the subsidiary data from a remote server.

22. The method of claim 1, wherein the subsidiary data comprises at least one of reference information regarding a program of the primary content data, biographical information regarding the actors, guests and participants of a program of the primary content data and advertisements.

23. The method of claim 1, wherein determining the identity of the primary content data is performed in response to a change in the primary content data currently displayed.

32. The method of claim 1 wherein displaying the subsidiary data comprises displaying the subsidiary data synchronous to the primary content data.

10. A machine-readable medium having stored thereon data representing sequences of instructions which, when executed by a machine, cause the machine to perform operations comprising:

receiving primary content data at an entertainment system from a primary external source;

receiving subsidiary data at the entertainment system from a subsidiary external source, the subsidiary data being independent of and supplementing the primary content data;

displaying the primary content data on a display device of the entertainment system;

determining the identity of the primary content data currently displayed by determining the time and channel corresponding to the primary content data currently displayed and accessing an electronic program guide using the determined time and channel;

determining whether subsidiary data supplementing the primary content data exists by accessing a storage database using the primary content data identity;

obtaining the subsidiary data identified in the storage database for display; and

displaying the subsidiary data on the display device of the entertainment system.

11. The machine-readable medium of claim 10, wherein the instructions further comprise instructions causing the machine to perform operations comprising:

receiving all of the subsidiary data corresponding to a program of the primary content data prior to beginning receipt of the program; and
