It would be humorous if sometimes when you opened your file in your Gdrive it was a media appropriate file containing an advertisement. Open it in a text editor get a text file ad, open it in an mp3 player get an audio ad, open it in a video viewer get a video ad. Not all the time of course, just now and then.
The ultimate endgame has to be a Google Online Bank, a Google Amazon, and a machine learning algorithms that bypasses advertising altogether and just buys you stuff before you even know you want it.
