Oh, I get what you are saying now, but why set the year at 1970?
The internet is just an evolution of the telegraph, which is just an evolution of semaphore, which is just an evolution of smoke signals and so on if one wants to put it that way...
So, you realize that precisely describes a telegraph, right!?
Any signal transmitting some data. In the times of telegraph there was no modern concepts of "data" and "digital". Also, information transmitted over telegraph in no way interfere with transmission itself. The concept of data networks managed by transmitted data was created only in 50s.
Just staying a fact even if they did not commonly use the terms.
Btw, when we're fiber optic multiplexers invented?
Cellular transmitters?
But, the broader point I was making is that it is arbitrary and wrong to claim some specific date as the last time we had "technological breakthroughs" every technology is just a refinement or adaptation of previous technology, it is a ladder not a springboard.
Agriculture has been practiced since prehistory in various forms and fashions, but Greg "agricultural breakthrough" happened when? Yet when compared to modern agricultural technology, the "agricultural revolution" might as well be foraging for nuts and berries.
Steam eninges existed since at least Archimedes' time, he made designs for them, yet not until the 18th century did they cause a "breakthrough"
Care to explain how you come to this completely incorrect conclusion?
A digital signal is one that transmits information only using two discreet states (1,0 or on,off etc.)
This is exactly how the telegraph operated, the circuit is either open or closed, and information was encoded and transmitted as a digital signal.
The fact that the Morse code used on telegraphs has variable periodicity to its signal ( .,-) does not make it non-digital because the fundamental mechanics of the device allow only on and off.
The earliest digital information transmitting, however, would be flashing a light or using reflective materials to flash sunlight in a purposeful pattern.

No, internet is evolution of digital data transmission that was invented and developed in 50s-60s.

Telegraphs weren't digital

Semaphore is an analogue signal medium.
