Yahoo! builds on audience targeting capabilities with interclick acquisition

Earlier today, Yahoo! announced that it has agreed to acquire interclick, a technology company whose solutions for data-driven advertising combine data and premium inventory with innovative audience-targeting technology. This acquisition signals further investment by Yahoo! in the performance display space and adds to Yahoo!’s industry leading targeting capabilities.

The interclick acquisition will benefit Yahoo! and our advertisers in two ways:

1. It includes a proprietary audience-targeting technology platform called Open Segment Manager (OSM).

2. It brings in a team that is experienced in selling audiences across varied sources of pooled supply.
