The first newspapers appeared in the 17th century, but ordinary people didn’​t use to buy them often because they were expensive. This changed in the 1850s with the invention of powerful printing presses, which could print 10,000 papers per hour. As a result, newspaper prices came down and more people could afford to buy them. Thanks to another new invention, the photograph, it was also the first time that newspapers contained pictures as well as articles.
When a volcano erupted on the Pacific island of Krakatoa in 1883, it killed 36.000 people. It was one of the worst natural disasters in history. It was also significant because it was the first time that news could travel around the world in minutes, using undersea electrical telegraph wires. Before the telegraph was invented, it used to take weeks far news to travel to a different continent. News of Abraham Lincoln's death, for example, took nearly two weeks to reach Europe in 1865.
In the early 20th century, before televisions became popular, people used to go to the cinema to watch the news. Ten-minute films called “news reels” contained moving images of four or five top news stories. The news reels were changed weekly, not daily, so the news wasn't always up to date. Nowadays, they are important as historical documents, as they provide the only audiovisual records of those times.
At the start of the 21st​ century, developments in smartphone technology and the growth at social media like Twitter, Facebook and Instagram have completely changed the way that we get our news. Now anybody can report news. This is sometimes called “citizen journalism.” One of the first and most famous examples of it happened in New York in 2009 when a plane carrying 150 passengers landed in the Hudson River after a flock of birds flew into the plane's engine. People who saw the crash posted comments and photos on Twitter and the news spread around the world in minutes. Professional journalists didn't arrive at the scene until 15 minutes later
