(Though it is a generally accepted we are in the Zettabyte era.)

Specialists interrogated the data for patterns in order to conduct fraud detection, measure marketing campaign effectiveness or grade insurance claim assessments.

Probability and statistical analysis (a tough and not a very popular career choice) became Business Intelligence that in turn evolved into Data Science (highly sought after and well paid).
