There is some debate as to whether indie development started before PCs with games developed for mainframe computers at universities and other large institutions. Games such as 1963's "Spacewar!" were not commercially financed and were made by a small team, but there lacked a commercial sector of the video game industry at that time to distinguish from independent works. However, one of the earliest known examples of games developed on contract for these systems was that of Joyce Weisbecker, who considers herself the first indie designer, as she had created several games for the RCA Studio II console in 1976 as an independent contractor for RCA.
