Here is an awesome and comprehensive summary of the transformation under-way in marketing. If you're in sales and struggling for leads, you might want to pass this on to your marketing colleagues and your exec team.
It's produced by Inbound Marketing Visionary, HubSpot, and I'm a HubSpot partner and fan, but that's irrelevant to the power and message in story. As a presentation critic, this one is a lesson in effective communication.
I highly recommend you take the 5 minutes to view it.
