Sistema Globo de Rádio (in English: Globo Radio System), or SGR, is a Brazilian media group owned by Grupo Globo that began with the inauguration of Rádio Globo in 1944, and today it has control of several other radios from different parts of Brazil. SGR also operates in the Pay-TV segment, where its radios offer music programming options to more than 6 million subscribers of Sky Brazil, Oi TV and Claro TV+ operators. In 1975, the SGR began to adopt a logo whose letters resemble that of Globo Network, made by Hans Donner with the color dark blue, with the name of "Sistema Globo de Rádio". In 2009, the SGR started to have a distinct visual identity of Globo, adopting a logo in the colors blue and gray, with the name SGR.
