Is the TAM issue that of TAM alone?

TAM is an organization that was started by the industry for the benefit of the industry- mainly the broadcasters and the advertisers. But, sadly what’s been happening for years is that none of the stake holders wants to take onus collectively to solve the issue of television ratings. Till the time the ratings of their respective channels are good broadcasters are happy. The moment they see a dip in the ratings they are up in arms against TAM alleging the ratings are fudged or are riddled with sampling and methodology glitches.
I have seen this happen so often in 17 years of my career. Infact when the ratings are good the channels themselves used to call and try to plant a story saying how well they have been performing. In my blog yesterday I had mentioned that its now etched in everybody’s mind that TAM is the only culprit. Nobody wants to think otherwise or ask questions to the other stakeholders. If there is a so much of an issue with TAM then why not collectively ouster TAM just as they did with AMAP, another rating agency that had been started to create competition and then died a death within 2 years of starting off. Why only two or three channels have decided to get themselves out of TAM subscriptions.
The recent issue has cropped up because MSM that runs SONY TV and MAX had an issue with TAM as the IPL ratings are far below than was expected.  How can anyone be so sure that everyone is dying to watch IPL? How do media organizations make such assumptions? Have they done some research on who is watching what?  
I guess it is important to understand the basics here that TAM did not start on its own in India. TAM was formed at the insistence of media owners (the top TV channels), advertisers (Indian Society of Advertisers) and agencies (Advertising Agencies Association of India). But, after the initial years the Joint Industry Body (JIB) decided to let TAM operate on its own with no collective dialogue whatsoever on any matters relating to TV ratings. TAM was supposedly the advertisers’ currency but today it is Broadcaster’s currency.
There has been several discussions on TAM’s monopoly and that there needs to another ratings agency. BARC (Broadcaster’s Audience Research Council) is therefore being launched. BARC is yet again a body formed by the industry stakeholders such as AAAI, ISA and IBF. Do you think that once BARC comes into play all will be hunky dory? What’s the guarantee that the ratings will not be fudged?
Competition is good. But will the industry be able to come together and support another research body when TAM has been evidently facing funding problems for all these years in terms of increasing people meters. Secondly, what’s the guarantee that after BARC is launched 30,000 people meters will suffice and that there will be no issues. If one goes by Dr Amit Mitra’s report the decision to arrive at 30,000 people meters was also in consultation with TAM.
According to me the ideal solution is to open dialogue supported by a systematic and a clear blueprint that will talk about the exact needs of the industry.
