Hi this is from Wikipedia; Brazilian Portuguese (Portuguese: português brasileiro or português do Brasil ; pt-BR) is a group of Portuguese dialects written and spoken by virtually all the almost 200 million inhabitants (2009) of Brazil and by a few million Brazilian emigrants, mainly in the United States, United Kingdom, Portugal, Canada, Japan and Paraguay. Roughly speaking, the differences between European Portuguese and standard Brazilian Portuguese are comparable to the ones found between British and standard American English. As with many languages, the differences between standard Brazilian Portuguese and its informal vernacular are quite significant, though lexicon and most of the grammar rules remain the same. Nonetheless, there are still scientific debates about the status of that variant due to those differences, especially whether or not it would be a case of diglossia. Nevertheless, the comparatively recent development of Brazilian Portuguese (and its use by people of various linguistic backgrounds), the cultural prestige and strong government support accorded to the written standard has maintained the unity of the language over the whole of Brazil and ensured that all regional varieties remain fully intelligible. Starting in the 1960s, the nationwide dominance of TV networks based in the southeast (Rio de Janeiro and São Paulo) has made the dialects of that region into an unofficial spoken standard for the means of communication.
