• a hardware processor that, when executing computer-executable instructions stored in the memory, is configured to:
• cause a representation of a first application to be presented, wherein the first application is related to a first object identified in a first media content item that is currently being presented;
• determine that the first media content item being presented has changed to a second media content item;
• and
• cause the representation of the first application to cease being presented and replacing the representation of the first application with a second application that is related to a second object identified in the second media content item being presented.

A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for managing a lifecycle of portable program modules, the method comprising:

• causing a representation of a first application to be presented, wherein the first application is related to a first object identified in a first media content item that is currently being presented;
• determining that the first media content item being presented has changed to a second media content item;
