Creating a New Civilization: The Politics of the Third Wave by Alvin
and Heidi Toffler
The First Wave: The Agricultural Revolution
The Second Wave: The Industrial Revolution
The Third Wave: The Information Revolution
"... the computer, and the television, and the telephone, are merging into
one ... this industry transformation will transform not just the way Bell
Atlantic behaves, but the way the public behaves - the way that we work,
and the way that we play, and the way that we learn ..."
Raymond Smith, CEO and Chairman, Bell Atlantic Corporation - Speaking
at National Net '94, April 7, 1994, Washington, DC
