Streaming media casts, such as in a video game or mobile device environment

A method for dynamically providing content during electronic game play, the method comprising:

• providing an assembly of content for presentation during game play of an electronic game program executing at a remote computing device, the electronic game program having zones representing functional areas within a game environment of the electronic game program, the content of the assembly being selected based on an identifier of a current electronic game program executing at the remote computing device, a current zone within the current electronic game program, and other information such that different content of the assembly is selected even though the identifier and the current zone are the same;
• receiving a metric indicating distance of a person from content within the current electronic game program to track whether the content was presented to the person;
• receiving an indication that a user is interested in making a purchase associated with content currently being presented;
• and
• notifying an advertiser of the interest of the user so that the user makes the purchase after game play
• wherein the assembly of content is supplemental to primary game content provided exclusively by the electronic game program,
• wherein the assembly of content is sent over a network in a series of multiple packets that are configured for reassembly at the remote computing device to be presented in association with the electronic game program, and
• wherein at least some of the multiple packets are presentable at or near arrival time at the remote computing device and before all of the multiple packets arrive at the remote computing device.

A system for dynamically providing content during electronic game play, the system comprising:

• a content providing system configured for providing, via a communication link, streamable content to one or more electronic game programs, each electronic game program executing at a remote computing device, wherein the streamable content is for presentation during game play and is supplemental to primary game content provided exclusively by the one or more electronic game programs, the content providing system including:
• a content accessing component configured to access content for use as streamable content;
• a content selection component configured to select content accessible by the content accessing component for use in one or more content streams;
• a content assembly component configured to assemble selected content into one or more content streams;
• a content dissemination component configured to disseminate one or more content streams to the remote computing device on which the one or more electronic game programs are executing for playing one or more content streams during game play of an electronic game program;
• and
• a component configured to receive from the remote computing device audibility metrics indicating audibility of content streams to the user and to track whether content streams were heard by the user, the audibility metrics indicating audible distance of a listener from a source of the audio within an electronic game program.
