CDO Hamburger invaded “Bahay ni Kuya” on the sixth eviction night of Pinoy Big Brother last November 2005. The “Ulam Burger” challenge was given to the remaining housemates Nene, Jayson, Franzen, Say, Cass and Uma. In this challenge, the housemates were tasked to cook CDO Hamburger and packed them with rice. Outside “Bahay ni Kuya”, the evicted housemates distributed the prepared “Ulam Burger Meals”.

The craze for Pinoy Big Brother rubbed off on CDO Hamburger. The Filipino people embraced CDO Hamburger just as they did with PBB. Such exposure in popular show established CDO as the leading brand in its category.
