SMMS retains contract for ITV's hit series Victoria
The agency, based in Hyde, worked on series one, which attracted 7.7 million viewers.
Jo Booth, co director of SMMS, said: “We started from nothing and built the online following up to 49k and counting.”
Producer Damien Timmer added: “The numbers alone speak volumes, but the campaign's success runs even deeper than that both here and abroad, in each fan feeling involved in the series due to the fantastic social media.”
Series two will document the next stage of Queen Victoria’s life and her marriage to Prince Albert and will include a two-hour Christmas special.
SMMS will be covering Twitter, Facebook and other aspects of online engagement.
