CampusNetwork, an on-campus social networking site called Campus Network that preceded Facebook, was created and popularized by Columbia engineering student Adam Goldberg in 2003. Mark Zuckerberg later asked Goldberg to join him in Palo Alto to work on Facebook, but Goldberg declined the offer. The Fu Foundation School of Engineering and Applied Science offers a minor in Technical Entrepreneurship through its Center for Technology, Innovation, and Community Engagement. SEAS' entrepreneurship activities focus on community building initiatives in New York and worldwide, made possible through partners such as Microsoft Corporation.
