Abstract
An audience data rating collecting system and method which are capable of collecting television audience rating data automatically within a short period of time. A broadcasting station transmits over the air a marker signal. The marker signal is received by terminal units associated with selected subscribers' television receivers. Upon reception of the market signal, and after waiting a period of time necessary for other terminal units within the system to transmit their data back to the station, each terminal unit automatically dials a predetermined telephone number at the broadcasting station. Once the broadcasting station has had time to automatically answer, data from that terminal unit representative of the channel then being viewed is transmitted over the telephone circuit to the broadcasting station. After all terminal units have called in, the results are tabulated.
