Steve Johnson (AOL)
Johnson-Grace is a data compression company based in the United States. The company was founded by Steve Johnson and Chris Grace in Newport Beach, California in 1992 to develop a generic spreadsheet technology for simulation modeling. The founders later talked to Irving Reed at the University of Southern California , mottoeng = "Let whoever earns the palm bear it" , religious_affiliation = Nonsectarian—historically Methodist , established = , accreditation = WSCUC , type = Private research university , academic_affiliations = , endowment = $8. ..., who had an idea for an improved image compression algorithm, and started implementing such an algorithm; this became the ART image file format. The company was acquired by AOL on February 1, 1996, for approximately 1.6 million shares of stock.

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entit ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 U.S. state, states, a Washington, D.C., federal district, five major unincorporated territories, nine United States Minor Outlying Islands, Minor Outlying Islands, and 326 Indian reservations. The United States is also in Compact of Free Association, free association with three Oceania, Pacific Island Sovereign state, sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Palau, Republic of Palau. It is the world's List of countries and dependencies by area, third-largest country by both land and total area. It shares land borders Canada–United States border, with Canada to its north and Mexico–United States border, with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the List of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signa ...

Newport Beach, California
Newport Beach is a coastal city in South Orange County, California. Newport Beach is known for swimming and sandy beaches. Newport Harbor once supported maritime industries however today, it is used mostly for recreation. Balboa Island draws visitors with a waterfront path and easy access from the ferry to the shops and restaurants. History The Upper Bay of Newport is a canyon carved by a stream in the Pleistocene period. The Lower Bay of Newport was formed much later by sand brought along by ocean currents, which constructed the offshore beach now recognized as the Balboa Peninsula of Newport Beach. For thousands of years, the Tongva people lived on the land in an extensive, thriving community. The Tongva villages of Genga and Moyongna were located in Newport Beach. Throughout the 1800s, Europeans colonized the land and forcibly removed and assimilated the Tongva. Present-day Newport Beach exists upon the unceded homelands of the Tongva people, and they have a historic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irving Reed
Irving Stoy Reed (November 12, 1923 – September 11, 2012) was an American mathematician and engineer. He is best known for co-inventing a class of algebraic error-correcting and error-detecting codes known as Reed–Solomon codes in collaboration with Gustave Solomon. He also co-invented the Reed–Muller code. Reed made many contributions to areas of electrical engineering including radar, signal processing, and image processing. He was part of the team that built the MADDIDA, guidance system for Northrop's Snark cruise missile – one of the first digital computers. He developed and introduced the now-standard Register Transfer Language to the computer community while at the Massachusetts Institute of Technology's Lincoln Laboratory. He was a faculty member of the Electrical Engineering-Systems Department of the University of Southern California from 1962 to 1993. Reed was a member of the National Academy of Engineering (1979) and a Fellow of the IEEE (1973), a winner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ART Image File Format
ART is a proprietary image file format used mostly by the America Online (AOL) service and client software. Technical details The ART format (file extension ".art") holds a single still image that has been highly compressed. The format was designed to facilitate the quick downloading of images, among other things. Originally, the compression was developed by the Johnson-Grace Company, which was then acquired by AOL. When an image is converted to the ART format, the image is analyzed and the software decides what compression technique would be best. The ART format has similarities to the progressive JPEG format, and certain attributes of the ART format can lead to image quality being sacrificed for the sake of image compression (for instance, the image's color palette can be limited). Usage by AOL The AOL service used the ART image format for most of the image presentation of the online service. In addition, the AOL client's web browser also automatically served such image ...
