Shares of radio broadcaster Clear Channel Communications Inc. (NYSE: CCU) were slightly up in early trading after the company posted higher first-quarter profit boosted in part by gains in its outdoor advertising unit. Though, the company was not able to beat analysts' predictions as the weak economy put pressure on the overall advertising market.

Clear Channel Communications announced that its quarterly profit surged to $799.7 million, or $1.61 per share. The income figures were definitely something to cheer about. During its first quarter last year, the company had net income of $102.2 million or 21 cents per share. Excluding one-time items, earnings for the quarter would have been $0.19 per share. Analysts' forecast (which typically exclude one-time items) was for $0.21 per share, according to Thomson Reuters.

The media and advertising display company also said that quarterly revenue rose 3.9% to $1.56 billion, compared with $1.51 billion reported in the same period a year ago, helped by favorable foreign exchange rates; excluding the effect of the week dollar, revenue rose only 1%. Analysts had been expecting to see slower sales of $1.53 billion.
