2000–2020: DZMM Dos por Dos was the brainchild of then-
DZMM manager Angelo Palmones. The program name was derived from the Filipino slang term for the length and width of a wooden jack. Network promotional material touted its hard-hitting commentary format as being likened to the strength of the jack's striking when it is being utilized for construction. Prior to getting the job of the show's program hosts, Taberna and Baja were concurrently serving as DZMM Radyo Patrol field reporters and already paired as co-anchors for the station's weekend current affairs show
Ito ang Radyo Patrol which they handled from 1999 to 2002 and the weekday early-morning newscast
Gising Pilipinas from 2001 to 2007. The program premiered on March 12, 2001, as a half-hour commentary program at the 7:30 am slot. Initially, the hosts tried to emulate the formal, high-brow and seriously-toned commentary programs of the time before retooling to exchanges of wacky banter interspersed between interview segments and field reports. This proved to be successful. The program expanded to an hour in 2006. Upon the launch of
DZMM TeleRadyo in 2007, the show was expanded to the late afternoon slot as a lead-in to the radio station's simulcast of
TV Patrol, a position it held until 2020. On January 10, 2011, due to programming changes, most notably with
Noli de Castro's
Kabayan moving to the 6:00 am slot, the morning edition of
Dos por Dos was moved to 5:00 am, more concentrating on early-morning field reports. With Gerry Baja's addition as co-host of the
ABS-CBN morning show
Umagang Kay Ganda in January 2012, the program was retooled again with its first fifteen minutes acting as a news rundown on simulcast with
ANC, DZMM TeleRadyo and DZMM-AM alongside
Umagang Kay Ganda. This lasted until March 1, 2013, when Taberna decided to concentrate on television duties, leaving Baja as solo host of a new program titled
Garantisadong Balita, which replaced the morning edition. On May 5, 2020,
Dos por Dos aired its final broadcast on DZMM-AM as a part of breaking news coverage surrounding the issuance of a cease and desist order from the
NTC against ABS-CBN's terrestrial broadcast assets as its legislative franchise expired the day before, with Taberna, Baja, and
Alvin Elchico anchoring the proceedings. It resumed on May 8 through cable on the provisionally-rebranded
TeleRadyo, with occasional pre-emptions on days when the House of Representatives scheduled hearings concerning the ABS-CBN legislative franchise. However, as a result of retrenchments following the
House committee vote denying the network a fresh legislative broadcast franchise, the show ended on July 31, 2020, with both Taberna and Baja's contracts terminated on the same date. Its vacated timeslot was absorbed by its former lead-in
Pasada sa TeleRadyo effective August 3, 2020.
2020–present: DZRH In the interim, numerous unconfirmed reports concerning the show's future circulated. Among those were reported talks between the hosts and
Radyo5 92.3 News FM, and
Super Radyo DZBB, while others postulated a possible split with Baja eyeing to move to
DWIZ. However, reported talks with
DZRH to accommodate the two were first disclosed through
The Philippine Star entertainment columnist
Ricky Lo. The move became confirmed and official on August 20, 2020, with the two hosts signing the contract within the
Manila Broadcasting Company's premises. DZRH anchor Deo Macalma further disclosed that the two hosts were greenlit by Ging Reyes to continue using the trademark name as it was not put up for patenting and registering by ABS-CBN. The transfer would also reunite the two hosts with the show's original creator Angelo Palmones.
Dos por Dos resumed as a 90-minute show on August 31, 2020, through
DZRH at 5:00 pm. Its format remained the same while adding a half-hour news rundown as a lead-off segment. In July 2021, the show, together with MBC, unveiled its advocacy
One Person, One Account: #AccountKoTo, with an objective of upholding wholesome discussions through "one social media account per person", and protection against
Internet trolls. In late July 2022, it was announced that the show would be transferring to the 6:00 am timeslot effective August 1; it aired on the afternoon timeslot for the last time on July 29. Following the program's move to the morning slot is that both Taberna and Baja also anchor DZRH's morning news programs
ACS Balita from 6:00 to 6:30 am and
Pangunahing Balita from 7:00 to 7:30 am, with the commentary and interview segments airing in between. ==Hosts==
