But the real challenge for 'Sang Linggo was the show's content itself as it tried to veer away from the usual noontime format of slapstick humor and various talent portions that its predecessor (and formerly a competitor on GMA Network) Eat Bulaga!
(now on TV5) (which added Allan K., Francis Magalona, Jose Manalo, Donna Cruz, and others to its roster of hosts as well) had presented to its viewers.
The show's rotating comedy sketch segments won loyal following out of new star combinations like the comic duos of John Estrada and Manilyn Reynes, Roderick Paulate and Jun Encarnacion, and Redford White and Norman Mitchell.
The biggest contribution however of the show to the noontime scene was the musical portion "Doon Po sa Jammin'" where the most popular and upcoming Pinoy rock bands were featured.
'Sang Linggo nAPO Sila barely celebrated its third year on Philippine TV when the show suddenly suffered in the ratings game.
continuing to thrill the noontime viewing public with "Super SiReyna", "Kaserola ng Kabayanan", and "Philippine Bulaga Association", the staff decided to give its still-popular segment "Calendar Girl" a more bolder, naughtier approach.
The question-and-answer portion was now handled by the newly established trio of John Estrada, Randy Santiago and Willie Revillame.
The APO Hiking Society was able to keep the Saturday noontime slot via the musical variety show "Sabado Live" which premiered on December 5.
After the axing of "APO", succeeding Kapamilya noontime shows would feature younger set of hosts with the same "street humor" inspired by their competitors.
