Brazilian tv isn't that great. I watch a lot of news broadcasts on Youtube from TV Brasil, Jornal da Gazeta, TV NBR. I use them because they(hopefully) use correct grammar. I sometimes use the Portuguese close captioning although that can be a little iffy. I never use English subtitles because it defeats the purpose in my opinion. I also have several blogger channels: Christian Figeiredo, Japao Nosso de cada dia, Street Smart Brazil, LubaTV, and Flavia Calina are a few. I like bloggers because they are speaking naturally or how they would daily as opposed to a tv show where there are actors reading scripts. You can also watch weather resorts or recipe videos to get used to numbers and giving directions in Portuguese.
