A2Z is a Philippine free-to-air blocktime broadcast television network based in Quezon City, with its studios located in Ortigas Center, Pasig.

The split comes after the release of GMA's 2018 financial report which declared the increasing lease payments that the network contributes to ZOE for the past three years (from ₱899.89 million in 2016 to almost a billion pesos in 2018).

It was rumored to be part of marketing the channel to either possibly continuing the analog simulcast of their sister station UHF 33 or for the airtime leasing.

[11][12][13][14] The programs of ABS-CBN News and Current Affairs were initially declined to broadcast on Channel 11 by the ZOE management due to editorial concerns until January 1, 2022, when TV Patrol officially began the simulcast of its weekend edition, and its regular edition on January 3, marking its return to free-to-air television, almost two years since the newscast made its final broadcast on the original Channel 2.

[21] On September 18, 2021, A2Z entered a partnership agreement with Philippine Collective Media Corporation for affiliation to broadcast the network via Channel 12 in selected parts of Eastern Visayas.
