ABS vs. GMA7: tv ratings war

This T.V. ratings war issue between ABS-CBN and GMA7 is the hot issue since before the year ended and it hasn't died down. It has gotten worse,in-fact, even the incident at the Manila Peninsula, which involved the handcuffing of media men and journalists, has become the issue between these two giant networks in the Philippines.

These issues started when ABS-CBN accused GMA7 had manipulated the ratings result by bribing the exposed households of AGB-Nielsen's respondents for survey of T.V. ratings. Personally, I am confused with this issue, if ABS-CBN is out there to throw shit on GMA7 just to rake ratings by exposing such anomaly on T.V. ratings, why would they expose it when they themselves are involved? It's like blowing themselves in deep shit! I think GMA7 has a lot of explaining to do and not just making their talents say on T.V. that they are proud to be "KAPUSO".
