In 2009, the IBOPE was under suspicion of a possible blackout in its system on 22 November 2009 at 9:40 at night. At that time, the device that measures real-time audience numbers stopped working, and the Institute accused mobile operators that they were responsible for the alleged breakdown in the system.

Since then, the television station determined on its department of communication not to disclose their numbers over the station's audience, as they say in their research methodologically.
