Spurred by its directory and games businesses, and by surging video revenue, Sohu, the Chinese portal, games and search group, reported revenues up by a quarter in the first three months of the year. Losses stabilized.

“Total revenues reached $455 million, up 25% year-over-year, which exceeded the high end of our prior guidance by $15 million,” said Charles Zhang, chairman and CEO of Sohu.com Inc. “Sohu Video’s advertising revenues grew 57% year-over-year, mainly driven by faster mobile monetization.”

Non-GAAP net loss attributable to Sohu.com Inc. for the first quarter was US$25 million, compared with net loss of US$48 million in the first quarter of 2014 and a net loss of US$14 million in the fourth quarter of 2014.
