UK media agency firm Aegis Group has acquired search engine marketer Range Online Media.  The purchase was made by Aegis’ search marketing arm, Isobar. Terms were not disclosed, although Aegis noted that the Fort Worth, TX.-based Range Online has gross assets of $12 million. Founded in 2001, Range Online initially focused on services aimed at retail and travel businesses. More recently it has expanded into the technology, luxury brands, financial services, utilities, and entertainment industries. Following the acquisition, Range Online Media will re-brand as iProspect and form the fourth US office in the iProspect global search network. This is the sixth acquisition Isobar has made in search marketing this year. Range Online ups iProspect’s reach to 21 offices in 17 markets worldwide. Release
