If you're a company or a brand who wants to reach millions of people, you can go to the likes of Google and Facebook and they'll do it for you. So what's the point of a media agency these days? For decades, big brands have been paying these firms huge sums to place them in all the right places. Josh Krichefski is CEO of the UK's largest, MediaCom, with clients such as Sky, DFS, and Tesco.
