The first highway of information is

Concept

A communication highway is a network or infrastructure that separates message movement from physical transport and carries information rapidly across distance.

In communication history, the earliest such electrical network predates film distribution and the Internet.

Application

The telegraph sent coded electrical signals over wired lines, allowing messages to cross long distances in minutes rather than travel with a person or printed sheet. This makes Telegraph the first information highway among the offered media.

Contrast

• Newssheets distribute printed information physically and depend on transport.

• The telegraph transmits coded messages electrically across a wired network.

• Films record and distribute audiovisual content, generally through physical copies or later broadcast systems.

• The Internet uses digital packet networks and developed much later.

Result

Therefore, the answer is Telegraph.
