LOS ANGELES — Shortly after raising an additional $40 million in venture funds, New York-based online video ad network Tremor Media is seeing advertisers begin to ink seven-figure ad deals in online video, the company's CEO Jason Glickman told Beet.TV.

That's because the amount of professional quality online video inventory has exploded in the last six to twelve months, which is luring advertisers to shift TV dollars to Internet TV, Glickman said.  "We are now seeing television and broadband merge, where advertisers are shifting and looking at online video upfronts." 

To shepherd that flow of money, a number of online video deals are GRP-based.  Using familiar TV metrics can help brands open their wallets to the Web.  Another contributing factor to the growth in large deals is the scale and scope of online video.  Tremor serves more than 1 billion video streams each month to more than 190 million unique users, a reach akin to many of the largest cable networks, Glickman said. 

On Monday, Tremor announced a deal with advertising technology firm Innovid to offer interactive pre-rolls across the Tremor network of sites.

We spoke with Glickman last week at the All Things Digital conference.
