I copied the attached image from a Google presentation slide.  It's a
great illustration of the many different ways that Google uses AI and
machine learning in the services it provides.  The speaker said it's
okay to use the image for educational purposes.

Here also is a link to recent article, not written by Google, that talks
in more detail about the different ways that Google uses AI in its
products:

One of the first points we try to make when teaching K-12 students about
AI is that AI technology is everywhere today.  It's not just for
self-driving cars, or Alexa and Siri.  Materials like this can help your
students appreciate the diversity of applications where AI is now a key
technology.
