While conceptual ideas about communication had been ocurring for centuries, its not really until the discovery of electro-magnetism in the 19th century that we can begin to have network communication. Central to our ability to have networks is devising mechanisms that can control and direct electrons so that electrons can be used to carry information. We will not successfully learn the physics of how to do this until about 1950. Between the period 1900-1950 electronic communication, though possible, is mostly inefficient and unreliable. As detailed below, by 1966 we have the means to construct the first version of the Internet and that was first launched in 1969 (the same year we landed on the Moon).
