How 'Star Wars' changed science fiction

The popularity of "Star Wars" shifted the market away from the more literary, and sometimes cynical, science fiction of the 1960s and '70s.

In time, though, writers like William Gibson would react against that and, in turn, create the "cyber punk" subgenre.

The story behind David Bowie's failed '1984' musical

The musician hoped to adapt Orwell's dystopian novel for the stage, though the project floundered after Orwell's widow—who found Bowie's vision in poor taste—refused to grant him the rights.

As the internet became more accessible in the '90s, fanfiction writers created websites dedicated to publishing stories about their favorite characters. Still, the hobby was far from mainstream.

Telling people you read or wrote fan fiction put you in the super geek category."

'The Stranger' remains a popular novel for teenagers

Camus' book's themes—alienation, transgression, and existentialism—continue to resonate with adolescent reader. That's also true of other popular teenage touchstones, like Aldous Huxley's "Brave New World," George Orwell's "Nineteen Eighty-Four," and Sylvia Plath's "The Bell Jar," which are still widely read—and assigned by high school teachers.

The 'Star Wars' series begins where George Lucas believed the story was most accessible

When renowned theoretical physicist Stephen Hawking did not rule out the possibility of time travel in his posthumous book Brief Answers to the Big Questions, many hopefuls got excited. But, unfortunately for them, Hawking believed that yet-to-be discovered laws of physics will prove time travel impossible. This piece outlines some practicalities about the speed of light and wormholes that lend way to Hawking’s prediction.

'Vox Pop' gave ordinary contestants the chance to win quick cash

The radio show began in 1932 with man-on-the-street interviews in Houston, but soon began traveling to different locations around the country.
