ABS-CBN Corporation, the country’s largest multimedia conglomerate, continues its winning streak since the start of 2011 with its locally-produced primetime programs leading the nationwide ratings.

According to Kantar Media/TNS, ABS-CBN led primetime TV with an average audience share of 40 percent or nine points higher than GMA’s 31 percent and TV5’s 16 percent for the period of Jan 1 to Feb 14.

Kantar Media/TNS data also show that ABS-CBN obtained a bigger average audience share of 36 percent for the same period (Jan 1 to Feb 14), which is higher than GMA’s 34 percent and TV5’s 13 percent.

According to ABS-CBN Corporate Communications head Bong Osorio, ABS-CBN primetime shows are doing so well that its drama series “Mara Clara” has wrestled the Mega Manila leadership from GMA on primetime.

Osorio noted that ABS-CBN’s top raters are all network-produced programs such as “Mara Clara,” “Mutya,” and “Imortal,” while GMA’s top raters are either produced by a blocktimer or a canned Korean series.

“ABS-CBN remains to be the national leader year-to-date (Jan 1 to Feb 14) without excluding some days based on the Kantar Media/TNS ratings data,” he said.

For the month of January 2010, ABS-CBN led in the national, balance Luzon, southern Luzon, Visayas, and Mindanao TV ratings.

For Balance Luzon, ABS-CBN obtained a 39% audience share, which was higher than GMA’s 35%.

More than half of the homes in Southern Luzon tuned in to ABS-CBN (56%) than GMA (25%).

In the Visayas, the number of Kapamilya homes was more than twice the number of Kapuso homes. 53% of the homes in the Visayas watched ABS-CBN shows while only 24% watched GMA.

In Mindanao, almost six out of ten homes watched ABS-CBN (55%) compared to only 19% watching GMA.

Kantar Media, a global market research group, offers audience research measurement systems in 32 countries. It started releasing its Philippine television audience measurement data in February 2009 with panels composed of 1,370 representative households covering urban Philippines and reporting on seven sectors namely the National Capital Region, North Luzon, Central Luzon, South Luzon, Visayas and Mindanao.

ABS-CBN shifted to Kantar Media/TNS after filing a case vs. AGB Nielsen Media Research for failing to comply with its request to investigate alleged cheating and data tampering in TV ratings. The case is still pending in court.
