DVD in the context of Jewel case

A library is a collection of books, and possibly other materials and media, that is accessible for use by its members and members of allied institutions. Libraries provide physical (hard copies) or digital (soft copies) materials, and may be a physical location, a virtual space, or both. A library's collection normally includes printed materials which can be borrowed, and usually also includes a reference section of publications which may only be utilized inside the premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs, Blu-rays, CDs, cassettes, or other applicable formats such as microform. They may also provide access to information, music or other content held on bibliographic databases. In addition, some libraries offer creation stations for makers which offer access to a 3D printing station with a 3D scanner.

Libraries can vary widely in size and may be organised and maintained by a public body such as a government, an institution (such as a school or museum), a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained experts in finding, selecting, circulating and organising information while interpreting information needs and navigating and analysing large amounts of information with a variety of resources. The area of study is known as library and information science or studies.

A supermarket is a self-service shop offering a wide variety of food, beverages and household products, organized into sections under one roof. The supermarket retail format first appeared around 1930 in the United States as the culmination of almost two decades of retail innovations to the grocery store, and began to spread to other countries after extensive worldwide publicity in 1956. In everyday American English usage, "grocery store" is often used interchangeably with "supermarket", while in other regions a supermarket is larger and has a wider selection, but is smaller and more limited in the range of merchandise than a hypermarket or megastore, which developed decades later.

The supermarket typically has places for fresh meat, fresh produce, dairy, deli items, baked goods, and similar foodstuffs. Shelf space is also reserved for canned and packaged goods and for various non-food items such as kitchenware, household cleaners, pharmacy products and pet supplies. Some supermarkets also sell other household products that are consumed regularly, such as alcohol (where permitted), medicine, and clothing, and some sell a much wider range of non-food products: DVDs, art supplies, sporting equipment, board games, and seasonal items (e.g., Christmas wrapping paper, Easter eggs, school uniforms, Valentine's Day themed gifts, Mother's Day gifts, Father's Day gifts and Halloween).

A television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for viewing and hearing television broadcasts. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode-ray tube (CRT) technology. The addition of color to broadcast television after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media for consumer use in the 1970s, such as Betamax, VHS; these were later succeeded by DVD. It has been used as a display device since the first generation of home computers (e.g. Timex Sinclair 1000) and dedicated video game consoles (e.g., Atari) in the 1980s. By the early 2010s, flat-panel television incorporating liquid-crystal display (LCD) technology, especially LED-backlit LCD technology, largely replaced CRT and other display technologies. Modern flat-panel TVs are typically capable of high-definition display (720p, 1080i, 1080p, 4K, 8K) and are capable of playing content from multiple sources, such as a USB device or internet streaming services.

Home video is recorded media sold or rented for home viewing. The term originates from the VHS and Betamax era, when the predominant medium was videotapes, but has carried over to optical disc formats such as DVD and Blu-ray. In a different usage, "home video" refers to amateur video recordings, also known as home movies.

Released in 1978, LaserDisc (LD) is another home video format, which never managed to gain widespread use on North American and European retail markets due to high cost of the players and their inability to record TV programs (unlike the VHS), although it retained some popularity among videophiles and film enthusiasts during its lifespan; the format had greater prevalence in some regions of Southeast Asia such as Japan, Hong Kong, Singapore and Malaysia where it was better supported. Film titles were released in LD format until 2001, production of LD players ceased in 2009.

A slipcase is a five-sided box, usually made of high-quality cardboard, into which binders, books or book sets are slipped for protection, leaving the spine exposed. Special editions of books are often slipcased for a stylish appearance when placed on a bookshelf. A few publishers, such as the Folio Society, publish nearly all their books in slipcases.

Protective slipcases have been issued for records, cassettes, 8-track tapes, film, video cassettes, compact discs, DVDs and even toys instead of or in addition to the more common jewel cases or keep case, and may be chosen for aesthetic or economic reasons. Larger slipcases that are designed to house one or more items are often used in packaging for special edition releases or box sets.

A wallchart is a type of large poster often displaying information for educational use or entertainment. One popular use of a wallchart is to track progress of sports teams in cup events.

During 2006 the practice of giving away wallcharts in British newspapers rose in popularity. Many papers including The Guardian, The Daily Mail and The Independent participated, with subjects varying from the "Sky At Night" to "British birds". Marc Sands, marketing director of The Guardian describes wallcharts as one of their most successful promotions excluding free DVDs in the Guardian editor's blog. The December 16 edition of The Guardian distributed a free 'Guide to Guardian Readers' wallchart illustrated by Posy Simmonds.

Video art is an art form which relies on using video technology as a visual and audio medium. Video art emerged during the late 1960s as new consumer video technology such as video tape recorders became available outside corporate broadcasting. Video art can take many forms: recordings that are broadcast; installations viewed in galleries or museums; works either streamed online, or distributed as video tapes, or on DVDs; and performances which may incorporate one or more television sets, video monitors, and projections, displaying live or recorded images and sounds.

Video art is named for the original analog video tape, which was the most commonly used recording technology in much of the form's history into the 1990s. With the advent of digital recording equipment, many artists began to explore digital technology as a new way of expression. Video art does not necessarily rely on the conventions that define theatrical cinema. It may not use actors, may contain no dialogue, and may have no discernible narrative or plot. Video art also differs from cinema subcategories such as avant garde cinema, short films, and experimental film.

In the United States copyright law, a copyright notice is a notice of statutorily prescribed form that informs users of the underlying claim to copyright ownership in a published work.

Copyright is a form of protection provided by U.S. law to authors of "original works of authorship". When a work is published under the authority of the copyright owner, a notice of copyright may be placed on all publicly distributed copies or phonorecords. The use of the notice is the responsibility of the copyright owner and does not require permission from, or registration with, the Copyright Office.

Blu-ray (Blu-ray Disc or BD) is a digital optical disc data storage format designed to supersede the DVD format. It was invented and developed in 2005 and released worldwide on June 20, 2006, capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X. The name refers to the blue laser used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs, resulting in an increased capacity.

The polycarbonate disc is 12 centimetres (4+3⁄4 inches) in diameter and 1.2 millimetres (1⁄16 inch) thick, the same size as DVDs and CDs. Conventional (or "pre-BDXL") Blu-ray discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs. Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BDXL re-writer drives.

A film distributor is a person responsible for the marketing of a film. The distribution company may be the same as, or different from, the production company. Distribution deals are an important part of financing a film.

The distributor may set the release date of a film and the method by which a film is to be exhibited or made available for viewing; for example, directly to the public either theatrically or for home viewing (DVD, video-on-demand, download, television programs through broadcast syndication etc.). A distributor may do this directly, if the distributor owns the theaters or film distribution networks, or through theatrical exhibitors and other sub-distributors. A limited distributor may deal only with particular products, such as DVDs or Blu-ray, or may act in a particular country or market. The primary distributor will often receive credit in the film's credits, one sheet or other marketing material.

An entertainment center (or centre), also known as an entertainment complex or a home entertainment center, is a piece of furniture designed to house consumer electronic appliances and components. It is sometimes a large cabinet with an exterior styled to appear like upscale furniture and an interior dedicated to electronic gear, such as home audio, television sets and video game equipment.

Antique or modern reproduction armoires or standing cabinets are used for entertainment centers, as are shelves and shelving systems. Part of the purpose of an entertainment center is to neatly house the many wires and cables that are associated with audio and video components, and they often contain dedicated areas (either drawers or other spaces) for storage of records, videotapes, CDs and/or DVDs.

DVD-Video is a consumer video format used to store digital video on DVDs. DVD-Video was the dominant consumer home video format in most of the world in the 2000s. As of 2025, it continues to compete with its high-definition Blu-ray Disc counterpart, while both receive competition as the collective delivery method of physical media by streaming services such as Netflix and Disney+. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on October 19, 1996 (with major releases beginning December 20, 1996), followed by a release on March 24, 1997, in the United States.

The DVD-Video specification was created by the DVD Forum and was not publicly available. Certain information in the DVD Format Books is proprietary and confidential and Licensees and Subscribers were required to sign a non-disclosure agreement. The DVD-Video Format Book could be obtained from the DVD Format/Logo Licensing Corporation (DVD FLLC) for a fee of $5,000. FLLC announced in 2024 that "On December 31, 2024, the current DVD Format/Logo License ("License") will expire. On the same date, our Licensing program, which originally started from 2000, will be terminated. There will be no new License program available and thus no License renewal is required."

In computing, an optical disc drive (ODD) is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, while other drives can both read and record. Those drives are called burners or writers since they physically burn the data onto the discs. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives.

Although most laptop manufacturers no longer have optical drives bundled with their products, external drives are still available for purchase separately.

The terms special edition, limited edition, and variants such as deluxe edition, collector's edition or expanded edition are used as a marketing incentive for various kinds of products, originally published products related to the arts, such as books, prints, recorded music and films, and video games, but now including clothing, cars, fine wine, and whisky, among other products. A limited edition is restricted in the number of copies produced, although in fact the number may be very low or very high. Suzuki (2008) defines limited edition products as those “sold in a state that makes them difficult to obtain because of companies limiting their availability to a certain period, quantity, region, or channel". A special edition implies there is extra material of some kind included. The term is frequently used on DVD film releases, often when the so-called "special" edition is actually the only version released.

A CD-ROM (/ˌsiːdiːˈrɒm/, compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains data computers can read, but not write or erase. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs).

During the 1990s and early 2000s, CD-ROMs were popularly used to distribute software and data for computers and fifth generation video game consoles. DVDs as well as downloading started to replace CD-ROMs in these roles starting in the early 2000s, and the use of CD-ROMs for commercial software is now rare.

A record shop or record store is a retail outlet that sells recorded music. Per the name, in the late 19th century and the early 20th century, record shops only sold gramophone records. But over the course of the 20th century, record shops sold the new formats that were developed, such as eight track tapes, compact cassettes and compact discs (CDs). Today, in the 21st century, record stores mainly sell CDs, vinyl records and, in some cases, DVDs of movies, TV shows, cartoons and concerts. Some record stores also sell music-related items such as posters of bands or singers, related clothing items and even merchandise such as bags and coffee mugs.

Even when CDs became popular during the 1990s, people in English-speaking countries still continued using the term "record shop" to describe a shop selling sound recordings. With the vinyl revival of the 21st century, often generating more income than CDs, the name is again accurate.

A video rental shop/store is a physical retail business that rents home videos such as movies, prerecorded TV shows, video game cartridges/discs and other media content. Typically, a rental shop conducts business with customers under conditions and terms agreed upon in a rental agreement or contract, which may be implied, explicit, or written. Many video rental stores also sell previously viewed movies and/or new, unopened movies.

In the 1980s, video rental stores rented VHS and Betamax tapes of movies; however, most stores dropped Betamax tapes when VHS won the format war late in the decade. In the 2000s, video rental stores began renting DVDs, a digital format with higher resolution than VHS. In the late 2000s, stores began selling and renting Blu-ray discs, a format that supports high definition resolution.
