2019.
The first paper covered a single corridor — EDSA, from Andres Bonifacio Shrine in Caloocan to the Mall of Asia in Pasay. It was called “Bus Transit System” at first. Then “Metro Busway Transit.” The acronym MBT was born early and never left.
In June 2020, the EDSA Busway launched — a dedicated median lane, proper boarding stations, one operator per route. The Yellow Line concept, written in 2019, was now operating. Nobody asked for it to happen that way. It just did.
The network grew from there. What started as one line became seven main BRT corridors, each with underlying feeder routes reaching into the barangays. By 2025–2026, the full name sharpened: Metro became Manila. Same three letters. More precise home.
