This Educational Technology list was created on February 10th, 1989. That was just five years after I graduated high school. I didn't discover it until many years later. But, it was initially founded by a group of graduate students and faculty at Michigan State University, lead by Vickie Banks Gaynor, to further communication among studetns and professionals in the field of educational technology.
