Radio Veritas (DZRV 846 kHz) is a Roman Catholic AM station owned and operated by the Global Broadcasting System, a member of the Catholic Media Network. The studio is located at Veritas Tower #162 West Avenue corner Epifanio delos Santos Avenue, Quezon City, and its transmitter is located at Barangay Taliptip, Bulacan, Bulacan sharing the same site of DZXL RMN Manila.
- April 11, 1969 – Radyo Veritas was inaugurated with Asian bishops as guests. Antonio Cardinal Samore represented Pope Paul VI. It began broadcasting on the frequency formerly assigned to DZST, another Catholic radio station formerly operated by the University of Santo Tomas. By that time, it was then owned by the Philippine Radio Educational and Information Center, Inc.
- November 29, 1970 – Pope Paul VI, on his pastoral visit to the country, blessed Radyo Veritas' studios with President Ferdinand E. Marcos in attendance.
- August 21, 1983 – Radyo Veritas became a byword with its coverage of events related to the assassination of former Senator Benigno S. Aquino Jr.
- February 22–25, 1986 – Radyo Veritas kept local and overseas audiences informed of events related to the People Power Revolution, after Archbishop of Manila Jaime Cardinal Sin called on the Filipinos to support Defense Minister Juan Ponce Enrile and Philippine Constabulary Chief Lt. General Fidel V. Ramos who had defected from the Marcos government. The three-day bloodless revolution eventually removed Marcos from power and installed Corazon Aquino as the eleventh President. Despite the blow-by-blow airing of the events during the EDSA revolt, several armed groups forced to destroy the transmitter of Radyo Veritas in Malolos, Bulacan, of which several personnel were hurt. By the same year, Radio Veritas awarded the Ramon Magsaysay Award for Journalism, Literature, and Creative Communication Arts for the station's role in delivering timely events during the 4-day revolution.
- May 17, 1991 – Radyo Veritas was acquired by the Global Broadcasting System from the original owner, Radio Veritas Asia of PREIC, and at the same time, it begun its commercial operations as DZNN (known as Kaibigang Totoo (Your True Friend) and The Spirit of the Philippines). DZNN also moved its studios to Makati City (later moved to Ortigas) and became home to notable broadcasters such as Louie Beltran, Ramon Tulfo, Rey Langit, Jay Sonza, Orly Punzalan and Dave Sta. Ana among others.
- January 16–20, 2001 – DZRV-Radyo Veritas was once again involved in Philippine history when Cardinal Sin used the station to rally Filipinos to the EDSA Shrine in what became the EDSA Revolution of 2001. Millions of protestors converged on the Shrine, eventually ousting President Joseph Estrada from Malacañang and handing power to his Vice-President, Gloria Macapagal-Arroyo.
- 2005 – A new management took over the operations of Radyo Veritas. That time, it launched its new logo and new programs centered on faith and religion. The longest-running station ID jingle of Radyo Veritas was retained. (with an exception of the "ZNN" part)
