Sherman Oaks-based Advertise.com, the online search engine marketing firm run by Dan Yomtobian, has been sued by AOL over the firm's domain name, according to reports. Apparently, AOL is suing Advertise.com over its similarity to AOL properties Advertising.com and Ad.com. Advertise.com was, until recently, known as ABCSearch. The Scour.com meta-search engine is also run by Yomtobian, and is an offshoot of ABCSearch.
