by Brian Dear
Thanks to the staff of the Computer History Museum in Mountain View, California, who in 2010 co-produced with me a two-day conference celebrating the fiftieth anniversary of the founding of the PLATO system. Five hundred people attended what turned out to be the largest event ever held at the museum up until that time. Thanks to Ray Ozzie and Microsoft Corporation for funding the recording of the full conference in HD video, which remains available online at http://youtube.com/platohistory thanks to the generous support of Google, Inc.
Thanks to Mike Cochran, Bill Galcher, Paul Koning, Steve Peltz, Paul Resch, Joe Stanton, Steve Williams, and Steve Zoppi for their incredible work creating and maintaining Cyber1, a publicly available, fully functioning PLATO system on the Internet, complete with much of CERL’s and CDC’s published catalog of lessons and games, available at http://cyber1.org. It has been an invaluable research tool.
Finally, I would like to express eternal love and gratitude to my wife, Patricia, whom I met via a TERM-talk on PLATO. She happily read and reread countless drafts and willingly shared—and endured—every moment of an eventful thirty-two-year journey that was the creation of this book.
Thanks to you, dear reader, as well.

Interview and Oral History Sources
The story of PLATO as a technological and cultural history is unusual. Unlike most such histories, there are no existing major books, magazine articles, documentaries, or other common sources to which historians may turn. So pervasive has the decades-long dearth of PLATO’s exposure been to popular culture and the media that published sources are few and far between. The academic literature has considerable relevant material, to be sure, but PLATO’s human story largely eludes the refereed journals. For an author seeking out the PLATO story this meant conducting hundreds of personal interviews and corresponding with an even larger set of people over more than twenty years. But whom to contact? Where to turn? An untenable situation was avoided by setting up a website, running since 1996, announcing the book project, describing its scope, listing questions for which the author was seeking answers, and—breaking no doubt some journalistic rules—listing out names of all who had been interviewed or had corresponded through the mail or online. That ever-growing list prompted ever more people to contact me: a virtuous cycle that has never stopped—it continues right up to the present day. The result is a book largely based on oral history, capturing, before they are forever lost, the stories of the people who participated in the late, great online community known as PLATO.
