Mobile game publisher Glu Mobile narrowed its loss, reporting a net loss of $4 million in the third quarter compared to a net loss of $56.9 million a year ago. Revenues totaled $19.6 million compared with $23.9 million a year ago.

In a statement, CEO Greg Ballard said the company remains optimistic that its recently launched titles for the iPhone will improve its paid app ranking. “We are also excited about the upcoming launch of our social network game initiative and anticipate our investment to gain traction as we develop and launch new titles in this growing sector of the gaming market,” he said.

Meanwhile, France’s Gameloft reported an 18 percent uptick in sales for the first nine months of this year, with third-quarter sales up 15 percent from a year ago. Mobile games accounted for 95 percent of the company’s third-quarter sales.

Gameloft attributes much of its success to games on Apple’s App Store and strong performance in the company’s Java and Brew games. North America represented 31 percent of the company’s third-quarter revenue, with its strongest growth taking place in Asia and South America.

Electronic Arts, parent company of EA Mobile, reports its earnings next week.
