Embodiment Construction

[0033] like figure 1 Described, in one embodiment, is media produced by production system 112 that includes a serial number or other preferably unique (or fully distributed) media identifier and preferably some media that includes content, e.g., audio, video , or other images, text, software or other storable content, at least some of which are encrypted or otherwise read-protected. The medium preferably includes at least a writable portion such as sequentially writable. The content is preferably provided in a relatively efficient manner such as by injection molding or other mastering techniques. Methods and apparatus that can be used in conjunction with making appropriate media, reading such media, and / or protecting content are described, for example, in U.S. Patent Application No. 09 / 315,398 filed May 20, 1999 (Attorney Docket No. .4154-1), U.S. Provisional Patent Application No. 60 / 140,633 filed June 23, 1999 (Attorney Docket No. 4154-2-PROV), or U.S. Patent Application N...

Abstract

Protected content is distributed to users without the need for payment at the time of media distribution. Payment can be performed at a later time in response to which content may be enabled, and / or users may selectively pay for, and receive enablement of, content such that only portions of content may be accessible at a given time. Following the first enablement of content, access rights may be expanded or otherwise changed, e.g., in response to a second payment.
