This invention refers to a system and a method of television audience measurements in real time through analysis of the content transmitted by the television broadcasting stations. The system hereby proposed includes a medium of detection of change of tuning state ( 2 ) of a television set ( 1 ), a means of generation of subscriptions ( 3 ) that generates subscriptions containing information on the content emitted by the television set obtained from the detection of change in the tuning state of the television set ( 1 ), a management device ( 30 ), a means of remittance of subscriptions ( 4 ) and an audience central, wherein the medium of remittance of subscriptions ( 4 ) sends the subscriptions generated by the medium of generation of subscriptions ( 3 ) to the audience central every time the said medium of detection ( 2 ) detects a change in the tuning state of the television set ( 1 ). This system is structurally simple and allows the measurement of television audience in real time quickly and at a relatively low cost. The method of the invention includes the stages of (a) detection of change of tuning state of a television set, (b) generation of subscriptions containing information on the tuning state of the television set obtained from the detection of change in the tuning state of the television set, (c) management and remittance of the subscriptions to an audience central, (d) comparison of the information contained in the subscriptions sent to the audience central with the information recorded in the audience central referring to the transported broadcasting stations and (e) identification of the broadcasting station that was being viewed at the moment of the generation of the subscriptions. The continuous repetition of stages (a) to (e) every time a change is detected in the tuning state of the television set ( 1 ), allows a monitoring in real time of the audiences measured for every one of the broadcasting stations transported to the audience central.
