Chinese online media company Sina.com announced Q4 revenue of $70.7 million, up 25 percent from $56.4 million in last year’s equivalent period. Net income grew 49 percent to $17.5 million ($.29 per share) from $11.7 million ($.20 per share). The company benefited from 40 percent year-over-year advertising growth. Non-advertising growth, mostly its wireless value added services business, slipped 1 percent, which is consistent with the weakness shown at companies like Linktone (NSDQ: LTON), affected by regulatory changes. On a sequential basis, revenue was up 10 percent. For the current quarter, Sina (NSDQ: SINA) is predicting revenue of $66-$68 million.
