The definition of entrepreneurship vary. Here are some examples:

Entrepreneurship, the pursuit of opportunity beyond the resources you currently control, is now a subject with segmented interest across a wide variety of fields and topics, including new venture creation, venture capital, social ventures, business model innovation, open software, internet, corporate entrepreneurship, global business, and biotechnology. — Haas School of Business

The concept of entrepreneurship was first established in the 1700s, and the meaning has evolved ever since.
To some economists, the entrepreneur is one who is willing to bear the risk of a new venture if there is a significant chance for profit. Others emphasize the entrepreneur’s role as an innovator who markets his innovation. Still other economists say that entrepreneurs develop new goods or processes that the market demands and are not currently being supplied.

In the 20th century, economist Joseph Schumpeter viewed entrepreneurship as a force of “creative destruction.” The entrepreneur carries out “new combinations,” thereby helping render old industries obsolete. Established ways of doing business are destroyed by the creation of new and better ways to do them.

Business expert Peter Drucker took this idea further, describing the entrepreneur as someone who actually searches for change, responds to it, and exploits change as an opportunity. A quick look at changes in communications – from typewriters to personal computers to the Internet – illustrates these ideas.
