In the aftermath of the launch of Scientific Atlanta by Glen P. Robinson and the subsequent disputes, Georgia Tech's culture encouraged hard work, but did not encourage start-ups. This changed during Joseph Pettit's administration; Pettit was at Stanford during the development of Silicon Valley and worked to change the culture to inspire something similar in Atlanta. "That was when Tech began actively encouraging faculty, staff and students to be entrepreneurial... In some ways it was a shift back to our roots, with Tech beginning to reconnect with the state through the Advanced Technology Development Center, the Economic Development Institute and the Georgia Research Alliance", according to Bob McMath.
