The history behind what we now know as a television goes back to 1920 when it was invented; nevertheless, it wasn’t until 1950´s when televisions became a house hold item. During the first years after the television´s invention, not many people had them in their houses; the reason being their price; it was too high for the masses, and decided to lower the price, without any success. Televisions were still not purchased by the majority of Americans; they just could not afford it. But, when their popularity started to rise, it happened almost overnight. In 1949, there were approximately, 1 million television sets and that number increased drastically; so much so that by 1950 there were 50 million sets in the houses of Americans.
Paul Gottlieb Nipkow was a German technician who invented the Nipkow disk, named after him; his invention was the most successful for television transmissions at the time.

Answer:
This road was called Royal Road.
Explanation:
The Persian Royal Road was an ancient road built by King Darius I in the 5th century. Dario built the road to provide rapid communication throughout his great empire from Susa to Sardis.
Archaeologists believe that the western part of the road was originally built by the kings of Assyria, as it proceeds through the heart of that ancient empire, by not following exactly the shortest and easiest way between the most important cities of the Achaemenid Empire. The eastern most parts of the road (now northern Iran) coincide with the largest known trade route, the Silk Road.
However, Dario I made the Royal Highway as it is known today by investing in the structure of the road and joining its parts completely, primarily as a fast mode of communication using the kingdom's pirradaziš, or messengers.
