Google adsense/adwords does CPM?

window.document.getElementById(‘post-3845’).parentNode.className += ‘ adhesive_post’;I was reading an old post on here where some people were claiming that Google adsense also does CPM ads? The idea was that if a large advertiser were to specifically target your site for ads that the ads could be shown as CPM rather than CPC. Is this true? :confused: I always thought adsense was CPC only.
If so is there any way of knowing, or has anyone had any experience with it happening on their sites?
