"Approximately 55% of US PR firms with an annual net revenue of $4m or less are outsourcing digital and social account work, according to a new survey of 800 PR agency CEOs by M&A consultancy the Stevens Group," according to a recent article in The Holmes Report. Why? 
"The agencies reported a lack of the necessary in-house capabilities required to keep up with client demand for digital, mobile, social media and online marketing services. While 70% of respondents said they are confident their agency is up to date as digital platforms change over the next two years, nearly 30% said they were not."
