An online television program information system extracts from a broadcast datastream of television program information only that program information for those shows which meet predetermined selection criteria, and stores only the extracted information. By not storing all broadcast television information, memory size for information storage is reduced and a high performance processor is not required for subset searches of the entire stored datastream for programs of interest. A low cost online television program information system is thereby provided, which may store large amounts of useful program information. Content selective storage is facilitated by transmitting and receiving the television program information in three groups, with the first group comprising event data, the second group comprising titles and the third group comprising descriptions.
