Brazil took the former low band VHF frequencies and moved AM stations there. The problem is that none of them are making money because nobody is buying new radios to hear them.
(Brazil, like the rest of the world outside of NARBA, never had daytimers. They just moved AM stations to the "low band" FM channels. There was enough space to accommodate them all even though Brazil had more AMs per capita than the US)
4 of those low band FMs are used for Radio Nacional's which I sometimes hear in the indiacativo de frequencia on Radio Nacional Amazonias 11780khz
