Leading Brazilian Internet Properties Gain Audiences Abroad
The top local Brazilian Internet properties were also found to be popular online destinations around the world, attracting substantial portions of their respective audiences from outside Brazil. The largest of these properties, Internet service provider and leading content portal, UOL, derived one quarter (24.7%) of its total traffic from outside Brazil, while international comparison shopping siteBuscaPeattracted 38.4 percent of its total traffic from audiences outside of Brazil.

“The popularity of Brazilian online content is growing both here in Brazil and around the world,” said Alex Banks, Managing Director of Latin American markets for Comscore. “The online medium has enabled Brazilian companies to not only develop their domestic consumer base, but also to attract incremental visitors from other countries – audiences that are not nearly as accessible via traditional media.”
