PAL-M is the analogue colour TV system used in Brazil since early 1972,^[1][2] making it the first South American country to broadcast in colour.

It is unique among analogue TV systems in that it combines the 525-line 30 frames-per-second System M with the PAL colour encoding system (using very nearly the NTSC colour subcarrier frequency), unlike all other countries which pair PAL with 625-line systems and NTSC with 525-line systems.

Colour broadcasts began on February 19, 1972, when the Globo and Bandeirantes networks transmitted the Caxias do Sul Grape Festival. Transition from black and white to colour on most programmes was not complete until 1978, ^{[3][4][5][6][7]} and only became commonplace nationwide by 1980.
