Internet Predecessors• Facsimile concepts in the mid 1800s;• Facsimile interoperability (infrastructure) over 125 years later;• Television was demonstrated in the late 1920s;• Television become marketable in the late 1940s;• Television really took off with color television in the 1960s;• Internet was supported by the U.S. Defense Department, then

through the National Science Foundation, department of Energy, NASA;
