When the IoIC approached us to carry out a piece of research into the size of the UK internal comms sector, we couldn't wait to get stuck in. Whilst relatively small compared with sectors we work with closely, such as HR, internal comms is experiencing healthy and steady growth, and we suspected that the true figure is now somewhat higher than the 20,000 we've heard thrown around in the past couple of years. And indeed it was. Want to know our magic number? Read the summary and the full report on the IoIC's website. We'd love to know your thoughts. Does this figure surprise you? Would you have estimated lower, or even higher? Please do tweet us or comment below.
