Another important development in the 20th century was the invention of the e-book.

We might think of the e-book as something more modern, a creation of the 21st century, but in fact, the first e-books made their appearance around the 1970s.

The free digital library, Project Gutenberg, named after the inventor of the printing press, launched in 1971.

The website's creator, Michael S. Hart, typed the United States Declaration of Independence into his computer.

In doing so, he created what was arguably the world's first e-book.

In the 1990s, new formats emerged.

E-books became easier to download and read.

But it wasn't until Amazon launched its e-reader in 2007 that e-books became mainstream.

The Kindle was an immediate success, transforming the book market over the next few years.

By 2012, e-book sales had surpassed the sales of hardbacks in the US.

When e-books first became popular, some wondered if print books would soon be a thing of the past.

But actually, while e-books continue to sell, making up about 20% of the market, most readers still seem to prefer a paperback.

In the UK, as many as 200,000 new titles are published each year.

One of the reasons that number is so high is the increase in self-published books, another interesting development.

Some see this as a positive change.

Getting published is now easier than ever, and a wider, more diverse range of authors can share their stories.

But others are skeptical.

Does the world need that many books?

Now, even AI is at it, churning out content of sometimes dubious quality.
