IAC/InterActiveCorp (IACI.O) said it expects the strong momentum in its search business to continue in 2011. Toolbars, which drive a majority of the company's quarterly search revenue, are browser add-ons that help users to search directly without visiting any website. "With toolbars being a good majority of the search business, you do have to be careful about the sustainability and overall revenue levels, given that the toolbars user is a short-lived customer," Benchmark Co analyst Clayton Moran said.
