Shirky clearly defines four major revolutions in media over the history of 500 years. Which of these do you feel are the most transformational in how journalists use personal and observational sources for reporting the news?

Answer and Explanation:

If we track back to history, papyrus is the very first invention through which books were produced. Moreover, it was only confined to the priests and the princes. Only they can decide which book they would make copies and which book will be banned.

As a scribe, Johannes Gutenberg invented movable types, which in result help to make the abundant production of books. Moreover, slowly, the importance of books and mass media started widely accepted by the world.

And then the newspaper London Gazette started publishing and printing.

And then technology came, and everything started changing entirely. Technology, where common people gave the grounds to write and express also there, is abundant of data that remains untouched. And publishers hire people to read their content and go through their ads. There is much difficult to differentiate between readers and the journalist. We are just a click away from posting any report and to scribe any piece of writing. Journalists now are open to write and express their views through their social media platforms, which are just based on their observations. The dilemma of accessing everyone from writing and publishing left no grounds for an authentic writer.

It took 600 years to score one million authors per year, but it took only five years to reach face book authors, blog writers, Instagram writers, and twitter writers.
