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

14. The machine-readable medium of claim 13, 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

storing the subsidiary data corresponding to the program locally.

15. The machine-readable medium of claim 14, wherein the instructions for obtaining subsidiary data comprises instructions causing the machine to perform operations comprising obtaining the subsidiary data from a local nonvolatile storage medium.

16. The machine-readable medium of claim 13, wherein the instructions for providing the subsidiary data further comprise instructions causing the machine to perform operations comprising:

determining an elapsed time of a program of the primary content data;

identifying a portion of the subsidiary data which corresponds to the program;

identifying a piece of the portion of the subsidiary data which corresponds to the elapsed time of a program; and

providing the piece concurrently with the primary content data.

17. The machine-readable medium of claim 16, wherein the instructions for identifying a portion of the subsidiary data comprise instructions causing the machine to perform operations comprising accessing a database which stores a plurality of portions of the subsidiary data.

18. The machine-readable medium of claim 13, wherein the instructions for determining the identity of the primary content data currently displayed further comprise instructions causing the machine to perform operations comprising reading an identifier included with the primary content data.
