Abstract: A computerized method enables an audience to synchronously interact with a broadcast program in realtime. A broadcast clock of a broadcast system is synchronized to a standard time. A server clock of a server computer is synchronized to the standard time using a network timing protocol. A client computer clock of a client computer is synchronized to the server clock. The program is broadcast synchronously to the broadcast clock. Web pages are provided by the server computer to the client computer. Responses generated by the client computer are time-stamped according to the synchronized time of the client computer so that the responses can be time-correlated to segments of the program.
