Ask.com, still trying hard (they’ve launched an unscrutable billboard campaign in LA, and other cities), will spend about $100 million in total ad spend this year, IAC CEO Barry Diller disclosed at the Reuters Global Technology, Media and Telecoms Summit today. Last week, Ask geared up a major television advertising campaign, which it expects to spend heavily on in June—normally the season that most Internet services scale back promotions as Web use typically softens in the summer months, says this Reuters story. Ask.com held 5.2 percent of the U.S. Web search market in March, up 0.2 percentage points over February, according to Comscore.
