I've just got my hands on the video used to open Mobile World Congress 2013
The first half is a full volume, fun romp through the massive growth of mobile over the past 20 years, and some predictions for the next 5. Well worth a watch. Some great stats in there for all watchers of mobile trends
The end bit focusses more on GSMA's role specifically, and what they do for operators. Which is maybe more niche.
Crank up the volume, turn off the lights, sit back and imagine yourself in a huge auditorium of high powered dudes in suits. You could almost be there, at MWC 2013 in person!
