Ted West, President and CEO of LookSmart, had this to say to explain the reasoning for the firm's lower-than-expected financial performance: "Our second quarter revenue results were impacted by an unanticipated softening in search advertising demand," commented Ted West, President and Chief Executive Officer. "We remain confident in LookSmart's business outlook and our ability to create value through the execution of our long-term business opportunities." Shares of ValueClick ( VCLK) fell by 19% to $11.23 after it lowered its profit and revenue forecast for its fiscal year 2008. The online advertiser now projects to earn 69 cents to 71 cents a share and revenue to be between $655 million and $675 million for the fiscal year.
