When the first issue of Reason was published in May 1968, hardly anyone knew what a video game was. But that was about to change. That same year, inventor Ralph Baer patented the interactive television device that would go on to become the world's first home video game console. The very first computer game, Spacewar!, was conceived by a Massachusetts Institute of Technology student just seven years before that. As Reason evolved into something bigger, so did interactive entertainment. Today, video games have leveled up to the top of the home entertainment heap. They're a $67 billion global business, and roughly half of Americans say they play them every week. Peter Suderman reviews how video games have just kept getting better and better since 1968.
