From the Script: SLIDE 15 - Foundation Languages

This chart shows the results of a University of Michigan Computer Science Department survey comparing foundation languages worldwide versus the US. For more specific information on this survey and on academic use in general, check out: http://www.acm.org/sigada/education/

A foundation language is the first one taught at a university.

We can see that, at the time this survey was taken in 1995, although Ada did not dominate as a foundation language (no one language did) - it did have the second highest percentage of use both worldwide and in the US.
