The Camarillo Christian media group, Salem Communications Corp., plans to confirm its fourth quarter guidance at a fastest growing business conference in Los Angeles next week, the firm said Thursday. The radio broadcaster, web content provider and book publisher announced last month it projects revenue to grow 2 percent to 4 percent in the fourth quarter when compared to the same period last year. Salem reported $54.1 million in revenue during the fourth quarter of 2010. The company said it will confirm guidance Thursday at the 4th Annual LD MICRO Growth Conference held in Los Angeles. In the third quarter, the company saw revenue jump 6.8 percent to $54.9 million when compared with last year.
