What earnings reports have revealed about ads

Here are highlights of recent quarterly earnings reports from selected Internet and media companies and what they say about the state of spending on advertising:

Thursday: Google Inc. says its revenue, after subtracting ad commissions, totaled $8.14 billion in the first quarter. Analysts were expecting revenue of $8.09 billion on this basis. Google's revenue was helped by a 39 percent increase in "paid clicks," but the prices of its search-driven text ads continued to decline. The so-called "cost-per-click" for these ads declined 12 percent from the same time a year earlier.
