Anomaly, which was launched in 2004 by the former Simons Palmer co-founder Carl Johnson and now has offices in New York and London, will use the backing to pursue an expansion strategy of launching offices in Brazil, China and mainland Europe.
MDC’s acquisition of the majority stake in Anomaly follows a similar deal with Los Angeles-based 72 and Sunny in December.
Anomaly has clients including Converse, Sony, Pepsi and Diageo and launched its London office in January 2009 with Paul Graham, previously the managing partner at Saint, the Rainey Kelly Campbell Roalfe/Y&R agency, as its founding partner.
Carl Johnson said: "Given the degree of independence we have all become used to it was essential that we are fuelled not controlled. MDC not only understands this but embraces it."
