One of the most frenetic areas of measurement development today is in cross platform. Creative and scalable solutions are being crafted that enable programmers and advertisers to gain a more complete picture of how the usage of various media platforms compare to and blend within each other. There is no standard yet, but there are a myriad of possible semi-solutions that can link some, but not yet all, platforms under one metric. Progress is being made and it is only a matter of time (and data) before we get to a complete and scaleable measurement.
