The death of Joy Guevarra after she and her friends played make-believe contestants of “Ano Ka Hilo?” on ABS-CBN 2’s “Magandang Tanghali Bayan,” focused national attention on the power of television upon the lives of men, women, and children. Concerned citizens were complaining that noontime shows, including “Sige, Ano Kaya Mo?” on GMA 7’s “Eat Bulaga,” were putting people’s lives in danger with the kind of contests they were promoting.
