What is Inbound Marketing?

I have heard a lot of buzz around the term "Inbound Marketing", so figured it would be a good idea to define the concept and share a great PowerPoint presentation from the VP of Marketing, Mike Volpe, over at Hubspot.

Inbound Marketing Defined:

"Inbound marketing is a style of marketing that essentially focuses on getting found by customers. This sense is related to relationship marketing and Seth Godin's idea of permission marketing. David Meerman Scott recommends that marketers "earn their way in" (via publishing helpful information on a blog etc.) in contrast to outbound marketing where they used to have to "buy, beg, or bug their way in" (via paid advertisements, issuing press releases in the hope they get picked up by the trade press, or paying commissioned sales people)." - Source: Wikipedia
