From The Art and Popular Culture Encyclopedia
A non-commercial enterprise is work that values other considerations above and beyond that of making a profit. It differs from a non-profit enterprise in that seeking a profit is a part of their business, just not the main part. A typical example is art that is being sold, but where the artist has strict rules about what they will and will not do. These rules significantly decrease profits (sometimes creating losses), but allow the artist to retain his artistic integrity.
