Dow Jones Newswires reports that Brazil’s largest internet service provider (ISP) by revenue, Universo Online (UOL), reported net profit of BRL25.1 million (USD15.6 million) for the three months ended 31 March 2011, up from BRL22.6 million a year earlier, driven by a strong rise in revenue. The company booked net revenue of BRL297.3 million in the period under review, compared with BRL183.1 million in 1Q10. Net subscription revenues stood at BRL100.4 million in 1Q11, 5% up on 1Q10, while net advertising and other revenues grew 124% year-on-year to BRL197.0 million, thanks to the organic growth of online advertising, products and data centre activities, in addition to the integration of corporate services unit DIVEO. Earnings before interest, taxes, depreciation and amortisation (EBITDA) reached BRL82.6 million for the first-quarter, up 108% from BRL39.7 million a year ago, it said. As at 31 March 2011 UOL counted 1.379 million paying broadband subscribers, equivalent to 78% of the total subscriber base, up 4% year-on-year. Paying dial-up subscribers reached 397,000 at the same date, broadly unchanged year-on-year.
