If you want to get into the head of one of online video’s (and online advertising in general) biggest brains, check out the latest DishyMix podcast from Susan Bratton. This week, she interviews Adam Gerber, CMO of Quantcast, an audience measurement company.

Adam was previously at Brightcove as their Vice President for Advertising Products and Strategy and is one of the smartest and most passionate people about online video.

Here’s what Susan had to say about Adam:

Adam Gerber has been a leader in the digital marketing space since it’s inception. He’s been an evangelist, a pioneer, spending solid budgets on digital media on behalf of his blue chip clients. He’s a believer. He’s amazingly smart. He’s a great man and you’ll enjoy knowing him better in this entertaining and informational interview. You’ll grow. You’ll learn. Enjoy!

For those of you who don’t know, DishyMix is a podcast featuring “Juicy Interviews with Famous Internet and Media People”, and hosted by Susan Bratton, in her own right a very famous internet and media person. We industry folks dig her…a lot. She is also the Chair Emeritus of ad:tech Expositions, the leading conference for digital marketers. She’s one of those people that everyone wants to know, and says they do. But thats not enough. You want her - NEED her - to know you. (Editorial Note: Not pandering. Susan and I know each other and have mutual friends. In fact, I was discussed in a recent DishyMix podcast. I just respect her that much and her hubby is cool, too. He invented Rhapsody, my personal choice for online music subscription services.)

So give a listen over the long weekend. And catch up on some of her previous podcasts while you’re there. Hell, its a long weekend. You don’t want to spend it all on YouTube.
