On November 25th APG and Campaign presented the 5th Battle of Big Thinking. This year's Battle played host to over 20 speakers drawn from the winners of winners from the previous events.

As always the approach was simple: three speakers per round, each given 15 minutes to present their big thought, after which the audience voted.

Delegates at the event enjoyed a diet of provocation, new ideas, neat and nickable observations, all served up in a great mixture of presentations and performance by the brightest people in the business.

And now you can enjoy this too.

For a limited time you can purchase the winning speaker videos from the day comprising over 2 hours of footage. The DVD of the presentations can be purchased for just £99. Click here to order now.
