Here is a blurb from Barry Miskind's excellent technical website ( http://www.thebdr.net/articles/haps.html )
"Brazil is in the process of moving AM stations to the FM band, specifically the 12 MHz originally occupied by Channels 5 and 6 - 76 to 88 MHz."
Obviously, the government has decided AM can not survive. Unlike Mexico, which moved 75% of its AM's to new FM allocations, Brazil's FM band is already quite well populated and could not accommodate the additional needs of AM moves.
And Brazil is perhaps more mobile/smartphone saturated than the US, yet they must believe that putting the AMs on what is essentially a new band can be successful even if streaming and media usage on phones is very high.
(As a note, in much of Latin America it was always very hard to get new landlines, often being a process that could take months or years and requiring the granting of gratuities to the folks at the phone company. So when mobile phones arrived, they were often a person's or a family's first phone and they took the place of landlines by default, no by preference. So in most nations, cellphone and smartphone ownership is comparable in percentages to that of the US)
