Interactive shop Definition 6 has bought PR and web services firm Leach Communications. Terms were not disclosed. This is Atlanta-based Definition 6’s second purchase in less than four months. In August, the company bought digital production and marketing firm Creative Bubble. The acquisition gives Definition 6 additional abilities, such as “SEO reputation management.” New York-based Leach also boasts of a wide array of interactive and social media PR techniques. The deals follow the $15 million in funding 12-year-old Definition 6 received from PE firm Navigation Capital Partners in July.
