New York--Online ad company DoubleClick Inc. said late Thursday that it broke even in the fourth quarter of last year. The result is better than analysts expected, but the company warned that it faced a loss in the current quarter because of lower media revenue. DoubleClick said its fourth-quarter pro forma net income was $216,000, compared with a loss of $1.78 million in the same period in 1999. DoubleClick said media revenue would decline 30% to 35% in the first quarter and 25% to 30% this year. Fourth-quarter revenue also topped most Wall Street predictions at $132 million, but a lack of meaningful profits continues to haunt DoubleClick, as well as its brethren in the dot-com space, according to Lazard Freres & Co. L.L.C. research analyst Dana Serman. Revenue from the sale of Internet advertising was up 19% and data revenue was up a scant 5%, while technology sales for its Dart platform showed a promising 114% increase from the same period a year earlier.
