The times they are a changing but when it comes to social media, change is constant and inevitable. So how do you harness the force of a platform that is shifting and disrupting itself? And what will 2016 look like for social media marketing?

In our final episode for 2015, Richard Spencer, head of agency at Isentia TwoSocial, drops by to chat with Mark and JV about who nailed and failed it in social media marketing this year. Richard also shares his thoughts on long-form content, the rise of the vertical video and wearable technology.

"I think the one defining constant is change effectively, and I think we as organisations are still learning how to use direct contact with consumers and stakeholders to great effect - we're still getting our head around how that fits as users," Richard said. "I think that's blurring the lines between how we're using the channel from an organisational perspective, from an HR point of view, from a customer service perspective, from a marketing and a communications perspective, from a direct sales perspective and all of those are, in effect blending into one."
