Abstract: The present disclosure relates to the field of digital information distribution. The last half-century has sen a manifold increase in the availability of information in a digital format. Such digital information, once created, can be copied any number of times without degradation of the original copy of the information. Furthermore, the information once digitized can, in theory, have an infinite lifetime. The present disclosure addresses the need to distribute digital information through various commercial transactions, wherein the lifetime of the distributed digital information is limited to a predetermined period of time. The present disclosure discloses systems and methods for the distribution of digital information on limited life optical media, wherein the limited life optical media includes a mechanism that physically and/or chemically limits the effective life of the digital information.
