Tremor Media and Visible World have teamed to target online advertising at an extreme, per browser level, reports MediaPost.

Visible World is launching a new Broadband & Wireless Division to add to its current cable TV operations. It has named Tremor its first online distributor.

Advertisers may purchase ads through Tremor's network, based on desired ZIP code. When a user pulls up a video that's part of the program, the Visible World system will identify their location and demographic. The system will also factor in current weather conditions. It will then deliver an ad variation based on those criteria.

With this targeting model, two different users watching the same video in the same household could potentially see two different in-stream ads.

Visible World expects car companies, TV networks and other such advertisers to benefit most from this method. Networks can presumably push shows just moments from when it is due to air, creating a kind of impulse buy.
