ABS-CBN Corporation, the country’s largest multimedia conglomerate, remains the undisputed leader on national primetime TV ratings in March (6PM-12MN) where it hit an average audience share of 42%, 12 points higher than rival network GMA 7's 30%.

The Kapamila network's teleseryes' compelling storytelling and content continue to grip viewers nationwide and get the highest TV ratings on primetime, when most of the Filipino viewers watch TV and which advertisers spend most for their commercial placements.
Kantar Media/TNS, the trusted global market research group that offers audience research measurement systems in 32 countries, reported that ABS-CBN got nine out of the top 10 most-watched programs last month with "Mara Clara" topping the list with 35.9% despite the new primetime offering of its rival station "Captain Barbell" that registered only a national TV ratings of  20.7%.

The eight other ABS-CBN programs that made it to the top 10 were "Mutya," (34.4%), "Minsan Lang Kita Iibigin” (33.1%), “Pilipinas Got Talent” (30.1%), “Maalaala Mo Kaya” (27.8%), "TV Patrol" (27.3%), “Rated K” (25.2%), “Imortal” (23.9%) and “Goin Bulilit” (22.1%).
ABS-CBN's primetime teleseryes likewise continue to beat GMA Network in Mega Manila, the erstwhile stronghold of the Kapuso network.  “Mara Clara” (29.1%) continues to pound rival show “I Heart You Pare” (21.4%) while “Mutya” (25.7%) and “Minsan Lang Kita Iibigin” (24.9%) remains dominant on their time slots and beat “Captain Barbell” (24.2%) and “Dwarfina” (23%) respectively.

“Mara Clara” (31.1%), “Minsan Lang Kita Iibigin” (26.2%) and “Mutya” (26.1%) are also the top three most watched programs in Metro Manila beating all other GMA offerings on all time blocks.

Its AM radio station DZMM performed strongly in the Nielsen Mega Manila RAM for January 2011.  DZMM obtained an audience share of 32.9 percent, easily eclipsing combined audience share of GMA Network's DZBB (16.4%) and Manila Broadcasting Corporation's DZRH (14%) for the same month. 
Overall, ABS-CBN's audience share for the first quarter reached 36% vs GMA’s 35%.
From January 1 to March 31, ABS-CBN managed to get all slots in the top ten most watched programs for the first three months of 2011 with “Mara Clara” still leading the pack with an average nationwide rating of 33.7% followed by “Mutya” (33.2%), “Minsan Lang Kita Iibigin” (33.1%), “Pilipinas Got Talent” (29.7), “Noah” (28%), “TV Patrol” (27.1%), “Imortal” (25.5%), “Maalaala Mo Kaya” (24.4%), “Imortal” (25.5%), “Rated K” (23.4%), “Wansapanataym” (21.8%), and “Goin Bulilit” (21.5%).
