One trend I've noticed with Google over the years is that they don't usually advertise on TV. There's been some commercials for the Nexus devices over the years, and recently some ads for Google Photos, but not much else. Google just uploaded a series of ads for Google Duo, their new video chat application, and they're absolutely adorable. Check them out:
There are a few others at Google's YouTube channel. I hope that Google will start to air these on TV soon, to help with its decreasing popularity on the Play Store.
