Market share analysis is an important part of market analysis and indicates how well a firm is doing in the marketplace compared to its competitors. Givon, Mahajan, and Muller have researched spreadsheet and word processing software firms to give a clearer image of how to determine market share in the software industry.

They propose six factors to help estimate the value of market share (1997): Unit or dollar sales, User base (since piracy and brand switching effect), Market definition (scope of definitions), Scope of denominator (which other brands included), Time frame length, Product definition (brand, product line, or strategic business unit).

A major resource of SHARE from the beginning was the SHARE library. Originally, IBM's operating systems were distributed in source form and it was common for systems programmers to make local modifications and to exchange them with other users. The SHARE library and the process of distributed development it fostered was one of the major origins of open source software. SHARE was later incorporated as a non-profit corporation based in Chicago, Illinois and is currently located at 401 N. Michigan Avenue. The organization produces a newsletter and conducts two major educational meetings per year.

Market share, in strategic management and marketing, is the percentage or proportion of the total available market or market segment that is being serviced by a company. It can be expressed as a company's sales revenue (from that market) divided by the total sales revenue available in that market.

It can also be expressed as a company's unit sales volume (in a market) divided by the total volume of units sold in that market. It is generally necessary to commission market research (generally desk/secondary research, although sometimes primary research) to estimate the total market size and a company's market share.

A share of stock is one of a finite number of equal portions in the capital of a company, entitling the owner to a proportion of distributed, non-reinvested profits known as dividends, and to a portion of the value of the company in case of liquidation. Shares can be voting or non-voting, meaning they either do or do not carry the right to vote on the board of directors and corporate policy. Whether this right exists often affects the value of the share. Voting and non-voting shares are also known as Class A and B shares respectively.

Investment management is the professional management of various securities (shares, bonds etc.) and assets (e.g., real estate), to meet specified investment goals for the benefit of the investors. Investors may be institutions (insurance companies, pension funds, corporations etc.) or private investors (both directly via investment contracts and more commonly via collective investment schemes e.g. mutual funds).
The term asset management is often used to refer to the investment management of collective investments, whilst the more generic fund management may refer to all forms of institutional investment as well as investment management for private investors.

Investment managers who specialize in advisory or discretionary management on behalf of (normally wealthy) private investors may often refer to their services as wealth management or portfolio management often within the context of so-called private banking.

An investment company is a company whose main business is holding securities of other companies purely for investment purposes. The investment company invests money on behalf of its shareholders who in turn share in the profits and losses. In finance, the money market is the global financial market for short-term borrowing and lending. It provides short-term liquidity funding for the global financial system. The money market is where short-term obligations such as Treasury bills, commercial paper and bankers acceptances are bought and sold.

Time-sharing refers to sharing a computing resource among many users by multitasking. Because early mainframes and minicomputers were extremely expensive, it was rarely possible to allow a single user exclusive access to the machine for interactive use. But because computers in interactive use often spend much of their time idly waiting for user input, it was suggested that multiple users could share a machine by allocating one user's idle time to service other users. Similarly, small slices of time spent waiting for disk, tape, or network input could be granted to other users.

Throughout the late 1960s and the 1970s, computer terminals were multiplexed onto large institutional mainframe computers (central computer systems), which in many implementations sequentially polled the terminals to see if there was any additional data or action requested by the computer user. Later technology in interconnections were interrupt driven, and some of these used parallel data transfer technologies like, for example, the IEEE 488 standard.

Generally, computer terminals were utilized on college properties in much the same places as desktop computers or personal computers are found today. In the earliest days of personal computers, many were in fact used as particularly smart terminals for time-sharing systems.
