While ad spending has been down since the economic recession started, there are signs that things are turning around. Yahoo, for instance, said that display ad revenue increased by 20 percent during Q1 2010 and saw a 24 percent increase in the “guaranteed display” business that includes its premium inventory.

“We are pleased with the improving trend from last quarter when display was down one percent,” wrote JP Morgan analyst Imran Khan in a note issued yesterday. “We are encouraged by 20 percent growth, which we believe highlights the potential for additional growth in the display business.”

Yahoo generated $1.59 billion during the first quarter, resulting in one percent revenue growth compared to the same quarter in 2009.
