Windows Live Hotmail Leads the Email Market While Google Gmail Posts Strong Gains in the Past Year

Sao Paulo, Brazil, February 2, 2010 – Comscore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released a report on the top web-based email and instant messenger applications in Brazil for December 2009. The data showed that Microsoft held the leading position in each category with Google and other brands demonstrating substantial growth.

“Microsoft continues to have a firm grip on many consumer applications in the Latin American marketplace,” said Alex Banks, Comscore managing director of Latin America. “However, several other consumer brands are also flexing their muscles in this developing market, including Google and Yahoo! It will be interesting to see how the competitive landscape changes over the next year or two with so many consumer-focused Internet brands taking part in this digital gold rush.”

Top Web-Based Email Applications

In December, more than 24 million Brazilians age 15 and older visited web-based email sites from home and work locations, up 18 percent versus last year, with a large majority of these users (20 million) accessing Hotmail. Google Gmail ranked second with 8.4 million visitors, up 51 percent from last year, followed by Yahoo! Mail with 7.1 million visitors (up 20 percent) and UOL Mail with nearly 4 million visitors (up 14 percent). Interestingly, 34 percent of Hotmail users also visited Gmail, while a far higher 81 percent of Gmail users also visited Hotmail.

Top Instant Messenger Applications

Microsoft holds an even more commanding position in the Brazilian instant messenger market, accounting for 96 percent of the 22.4 million visitors to the category. However, while the category on the whole is growing significantly more slowly (up 5 percent) than the total Brazilian Internet audience (up 20 percent), several smaller players in the instant messenger category are growing at substantial rates. Second ranked EBuddy.com grew 330 percent in the past year to 1.8 million visitors, followed by Meebo with 840,000 visitors (up 103 percent) and Iminent.com with 686,000 visitors (up 1,236 percent).
