At the recent VideoNuze 2012 Online Video Advertising Summit, eMarketer's principal analyst David Hallerman presented data on the state of the online video advertising market. While bullish about its prospects for growth, one of David's clear message was that TV advertising isn't going away any time soon, and in fact the growth of ad dollars TV will experience over the next 5 years will actually be greater than online video's.

In David's presentation, he explains the key factors he believes will hinder or help online video's growth. No surprise, one of the most important is unified measurement. Overall, David sees online video advertising as being complimentary to TV advertising. At the end of the session I join him on stage for 10 minutes of Q&A.
