A whiteboard (also known by the terms markerboard, dry-erase board, wipe board, dry-wipe board, pen-board, and the misnomer greaseboard) is any glossy, usually white surface for nonpermanent markings. Whiteboards are analogous to blackboards, but with a smoother surface allowing rapid marking and erasing of markings on their surface. The popularity of whiteboards increased rapidly in the mid-1990s and they have become a fixture in many offices, meeting rooms, school classrooms, and other work environments.
The term whiteboard is also used metaphorically to refer to features of computer software applications that simulate whiteboards. Such "virtual whiteboards" allow one or more people to write or draw images on a simulated canvas. This is a common feature of many virtual meeting, collaboration, and instant messaging applications. The term whiteboard is also used to refer to interactive whiteboards.

History
According to one account, whiteboards were invented by Martin Heit, a photographer and Korean War veteran. When he accidentally marked a photographic negative with a marker and tried to wipe it off, he realized the marker ink came off very easily. He created a whiteboard with a laminate similar to that found on photographic negatives. The night before he was set to unveil his invention at a trade show, his prototype was destroyed by a fire. Rather than create another prototype, he sold his patent to Dri-Mark.
The second account is that Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Whiteboards became commercially available in the early 1960s, but did not become widely used until 40 years later. Early whiteboards needed to be wiped with a damp cloth and markers had a tendency to leave marks behind, even after erasing the board. Dry-erase markers for whiteboards were invented in 1975.
Whiteboards started becoming commonly used by businesses in the early 1990s. They became more common in classrooms during the 1990s due to concerns over health problems in children with dust allergies and the potential for chalkdust to damage computers. By the late 1990s, about 21% of American classrooms had converted from chalkboards to whiteboards.
Types
The first whiteboards were very expensive and were made of an enameled steel. Cheaper versions were then produced, including laminated chipboard, high-pressure laminates and steel boards with a white, usually polyester or acrylic, coating. Enameled whiteboards, also referred to as porcelain, and sometimes glass boards, have the advantage that markings can be erased completely; other materials tend to become stained over time. Enameled boards are more expensive and less used in commercial environments, but in more demanding environments with heavier use, such as educational establishments, porcelain boards are considered superior.
Other types of dry marker boards are also available, such as high gloss vinyl and coated paper, which can be rolled up, high-density two-part high gloss paints, glass and coated acrylics and polypropylene magic whiteboards which use static electricity to cling to walls, windows, and doors.
Clear marker surfaces, made of glass or specially coated acrylic, became available around the mid-2000s. They are generally manufactured from technical glass, e.g. for monitor screen filters, which is optically coated.
Adhesive whiteboards
Whiteboard material can be bought in rolls, sheets, and pre-formed boards. Adhesive whiteboards come in either a sheet or a roll and feature a stick back enabling the user to create a custom size board or project with the material. Although adhesive whiteboard material does not come in a thick, hard glass or painted steel plate, the melamine allows for a flexible material while preserving the high-quality whiteboard attributes of other surface materials. Adhesive whiteboards allow for custom projects such as dry erase wall calendars, whiteboard tables, cupboard grocery lists, indoor games for kids, and more.
Erasable marker
The whiteboard pen (also called a whiteboard marker or dry erasable marker) was invented by Jerry Woolf of Techform Laboratories and later patented by Pilot Pen in 1975. It is a non-permanent marker and uses an erasable ink that adheres to the writing surface without binding to or being absorbed by it. Applications range from temporary writing with acetate sheets (for use with overhead projectors) to whiteboards and similar glossy surfaces. The erasable ink does not contain the toxic chemical compounds xylene and/or toluene, unlike permanent markers.
Surface materials
There are six types of materials commonly used for whiteboard surfaces:
Polypropylene film
Innovation resulted in the use of polypropylene film. Polypropylene film has the ability to get statically charged which enable users to cling it to every surface. It works wth dry whiteboard markers and wipes. Whiteboards are reusable and materials are recyclable.
