Media business became big in the 1830s, partially due to the development of , which allowed for mass production of newspapers, books, and magazines.

The correct answer is the steam-powered printing press.

Explanation:

On November 28, but in 1814, a world steam press operated for the first time and went to edit the Times newspaper in London. The first was invented by German Frederick Koenig, but Willian Nicholson had developed rotary inking. Until the appearance of these inventions, the only existing machines were powered by the wind, water and muscles of men and animals.

Frederick Koenig, was born in 1744, in Leipzig (Germany). He, like Gutenberg, was obsessed with printing. He wanted to find a system that would allow more rapid printing and less work, but he also had no money and needed a capitalist partner to carry out his ideas.

Koenig's press was a steam printing machine. The shape remained on the stage, it moved thanks to the energy of the steam, made the sheet of paper I was printing, and then withdrew. This meant that the sheets of paper could be placed in place and removed without interruption.

Mechanical Presses

Explanation:

During the beginning of the 19th century, the first improvement to wooden hand press in nearly three half centuries was the emergence of iron hand press. All metal Stanhope press was then invented later in 1803 and used a couple of compound levers to create a bigger downward pressure. Then, printers started producing complete folio in one pull and thereby raising daily output.

A German whose name was Friedrich Koenig made a landmark achievement in the printing world in the year 1811 when he invented steam driven, flat - bed cylinder press which was capable of printing at more than five times, the speed of Stanhope.

After his invention, printers became able to produce more than one thousand sheets each hour. Then later in the year - 1830, the world began to use MECHANICAL PRESSES. and as a result, media businesses started becoming big due to the development of mechanical presses which helped greatly in mass production of newspapers/magazines/books.
