The survey was conducted back in January. According to their figures, Gato Sabido is the largest Brazilian ebook retailer with 7,292 ebooks in Portuguese. Saraiva, a Brazilian media retailer, came in second with 6,058 titles. Amazon, who hasn't yet opened a local Kindle store in Brazil, came in third (3,849 titles in Portuguese).
But when it comes to publishing ebooks, Saraiva takes the lead. They have over a thousand titles out now, and they actually have more of their own titles available via Gato Sabido than their own ebookstore.
I'm still waiting to see if I can get a copy of the report. I'll post a link if and when I can. I'm still searching for a good set of statistical data on the Brazilian market, if I find it I will post that too. But let me give you a perspective on on how small ebooks are in Brazil.
There are 11,000 ebooks now on the market, but there are over 52,000 titles published each year in Brazil (the backlist probably measures in the low millions). This market is still in its infancy.
