The company I work for allows targeting of advertisements based on the video content on a page. We do track users by dropping a cookie (so that we can calculate GRPs) but make no attempt to identify or behaviourally target users - we don't believe either are very effective for brand-building, which is our target market; it's about having your brand associated with certain content, not patterns of browsing. A lot of people at work use AdBlock - even the operations people who spend a lot of their time looking at (and for) ad-laden pages will often have one browser with and another without, or will browse in Incognito mode when they need to see ads. I've long found it a bit ironic...
