One of our early sessions at the recent Video Ad Summit was "TV is Video, But is Video TV?" which included Doug Knopper (Co-CEO, FreeWheel), Peter Naylor (SVP, Ad Sales, Hulu), Fred Santarpia (EVP, Chief Digital Officer, Conde Nast Entertainment) and Dan Suratt (EVP, Digital Media and Business Development, A+E Networks), with me moderating.

The question is highly relevant as it influences how ad spending will evolve and how pay-TV's value proposition will be perceived given the proliferation of online originals. Our panelists offer a range of perspectives, with some consensus that if it's long-form, high-quality, rights-managed and brand-safe online video, there's no practical difference vs. TV. One data point that Peter shares - that 62% of Hulu's content is now viewed on connected TV devices - underscores how mainstream online video viewing has become.

However, panelists cited various factors that create friction in the monetization of video, such as cross-screen measurement, viewability and adoption of particular TV ad business practices. The panelists discuss these factors, how they're being addressed and the timeline for resolution. Overall it's a fascinating discussion of how online video and TV are continuing to merge.
