MNT was founded on March 15, 1979 by entrepreneur and politician José Carlos Martinez as a local station called TV Polar, originally affiliated to Nia Network until it was sold to Diários Associados in 1980. In 1982, the station was renamed as Rede ON, and was subsequently renamed as MNT in 1993 after becoming a national network the previous year. MNT is currently chaired by entrepreneur and politician (and brother) Flávio de Castro Martinez, who took over after José Carlos Martinez's death in 2003.[1]
