Brazil has a lot of small, very small, ISPs. There was a law some time back that boosted the market for smaller ISPs. On my street I have a small ISP that only runs cables and internet to a portion of my neighborhood. However, those smaller ISPs are usually buying their connection from the few giant companies in the business and redistributing it through their own means. Crazy part though: often they have better prices and support when compared to the giant ISPs they’re buying their internet access from.
