Hi all so I logged onto my channel today and was just checking out stuff and then I noticed an odd spike on my earnings (from pretty well nothing to a little more then nothing xD) I clicked on it and had a $398.98 CPM for a video playback! 
Got me thinking how high can CPM go?! So what's the highest everyone has seen???
