Which technology first marked a separation between transportation and communication?

The telegraph first marked a separation between transportation and communication.

Before it, a message could travel only as fast as a person, ship or train could carry it.

The electric telegraph let information move independently of any physical vehicle, and far faster.

Projection is a display technology and never governed the movement of messages over distance.

Printing multiplied copies but still relied on physical transport to distribute them.

Photography fixed images and, like print, depended on carriage to spread, so it did not sever the two.
