James Hall created Semantica with the idea of creating video content developed specifically to teach Portuguese of Brazil as it's really spoken. James and his team believe that the best way to teach the language is to present video content that is contextual and tells a story. For language learning online this is the most effective approach. (Semantica 2018) I have been using Semantica for a couple months and can honestly say that it is a great video series to learn Brazilian Portuguese. There are beginning, intermediate and advanced series.
