(Formerly Nasdaq:MASC, now part of Computer Associates)

In 1996, Mastering Computers, a leading information technology (IT) training company with nationwide operations, was acquired by Eagle River Interactive, a public company founded and led by Terry Graunke. Mastering Computers leveraged Eagle River's interactive development capabilities to create a computer-based training library of more than 300 titles. The company also drew on its public parent's financial assets to expand its product line significantly into higher-margin training products and to expand geographically into Europe.

In 1997, Eagle River sold its interactive development business to Omnicom Group, one of the world's largest holding companies of advertising agencies and marketing services companies. The public company changed its name to Mastering, Inc. and focused on its IT training business, a more predictable, higher-margin, and faster growing business.

After growing Mastering from a $10 million business to a company on track to realize revenues of more than $50 million two years later, Mastering was acquired in early 1998 by PLATINUM technology in a transaction valued at more than $225 million.
