TRAI pointed out that it had submitted recommendations on the same issue in 2008, but the ministry as well as the industry made "little or no progress" on the suggestions.
In a statement released while issuing fresh guidelines today, TRAI said that "implementation has now become a critical factor" and it would not continue to be a mute spectator and may suo motu intervene in larger public interest.
When asked what intervention TRAI could take its chairman Rahul Khullar said, "We can do a lot."
The latest TRAI recommendations on TV rating agencies support self regulation of TV ratings through an industry led body like Broadcast Audience Research Council (BARC).
TV rating agencies should have a minimum of 20,000 panel homes for collecting viewership data and this number should increase by 10,000 every year till the figure of 50,000 is reached, TRAI recommended.
It also said that any agency which can meet the eligibility conditions should be allowed to register with the I&B ministry for doing the rating work.
