The methodology used by TAM for audience measurement has come under the scanner on two major counts - the small size of the audience sample and the possibility of manipulation of people meters. (People meters are gadgets attached to the television set which automatically record the television-viewing details of the people using the set.) TAM Media Research has about 8,150 people meters installed across the country, which monitor the TV-viewing habits of approximately 33,500 people.
Whoever has TAM gadgets only will help in increasing TRP !!!
