RatDVD (originally stylized "ratDVD") is the name of a proprietary container format for digital video, developed by Peter Jensen and a group of Russian and Danish university students.
 The container format is a compressed archive format that holds all features of DVD-Video in a single file.
 Unlike other container formats like Matroska, it is designed to accurately mirror the exact feature set of standard video DVDs, facilitating round-tripping back to the DVD-Video format.
Steve Wilhite of CompuServe was the engineering lead on the team that adapted the GIF file format, which went on to become the de facto standard for 8-bit color images on the Internet until PNG became a viable alternative.
 Steve Wilhite developed the GIF (Graphic Interchange Format) in 1987.
 By 2016, the format had found mainstream use in website design, social media posts, workflow documents and how-to guides.
Stephen Richard "Steve" Wright (born 26 August 1954 in Greenwich, London) is an English broadcaster, widely credited for creating the zoo format, with its zany, multi-personality approach.
 He presents 'Steve Wright in the Afternoon' and 'Steve Wright's Sunday Love Songs' on BBC Radio 2.
 He rose to prominence in the early 1980s while working with Peter Dickson on BBC Radio 1.
 His childhood ambition was to work in the entertainment business.
 After a variety of jobs, Wright got his big break in the 1970s at Radio Luxembourg, where he presented his own nightly show before joining the BBC in 1980 to present the Saturday night slot on Radio 1.
 He famously moved to daytime on Radio 1 in 1981 with 'Steve Wright in the Afternoon' which revolutionised radio by introducing the zoo format to the UK.
 Wright has won a stackful of awards, including Best DJ of the Year as voted by readers of "The Sun", the "Daily Mirror" Readers Poll and by Smash Hits in 1994.
 In 1998, he was awarded TRIC Personality of the Year for his radio programmes.
Windows Media Audio (WMA) is the name of a series of audio codecs and their corresponding audio coding formats developed by Microsoft.
 It is a proprietary technology that forms part of the Windows Media framework.
 WMA consists of four distinct codecs.
 The original WMA codec, known simply as "WMA", was conceived as a competitor to the popular MP3 and RealAudio codecs.
 "WMA Pro", a newer and more advanced codec, supports multichannel and high resolution audio.
 A lossless codec, "WMA Lossless", compresses audio data without loss of audio fidelity (the regular WMA format is lossy).
 "WMA Voice", targeted at voice content, applies compression using a range of low bit rates. Microsoft has also developed a digital container format called Advanced Systems Format to store audio encoded by WMA.
The Music Encoding Initiative (MEI) is an open-source effort to create a system for representation musical documents in a machine-readable structure.
 MEI closely mirrors work done by text scholars in the Text Encoding Initiative (TEI) and while the two encoding initiatives are not formally related, they share many common characteristics and development practices.
 The term "MEI", like "TEI", describes the governing organization and the markup language.
 The MEI community solicits input and development directions from specialists in various music research communities, including technologists, librarians, historians, and theorists in a common effort to discuss and define best practices for representing a broad range of musical documents and structures.
 The results of these discussions are then formalized into the MEI schema, a core set of rules for recording physical and intellectual characteristics of music notation documents.
 This schema is expressed in an XML Schema Language, with RelaxNG being the preferred format.
 The MEI schema is developed using the One-Document-Does-it-all (ODD) format, a literate programming XML format developed by the Text Encoding Initiative.
The Graphics Interchange Format (better known by its acronym GIF or ) is a bitmap image format that was developed by US-based software writer Steve Wilhite while working at the bulletin board service (BBS) provider CompuServe on June 15, 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.
Sequence Alignment Map (SAM) is a text-based format for storing biological sequences aligned to a reference sequence developed by Heng Li.

</ref> It is widely used for storing data, such as nucleotide sequences, generated by Next generation sequencing technologies.
 "The format supports short and long reads (up to 128Mbp) produced by different sequencing platforms and is used to hold mapped data within the GATK and across the Broad Institute, the Sanger Centre, and throughout the 1000 Genomes project.
 Sequence Alignment/Map (SAM) format for alignment of nucleotide sequences (e.g. sequencing reads) to (a) reference sequence(s).
 May contain base-call and alignment qualities and other data."
Viscosity is also an out-of-print image and animation editing utility published by Sonic Foundry.
 It can work with PNG, GIF, JPG/JPEG, BMP, AVI and its native VSC format.
This is a list of file formats used by computers, organized by type.
 Filename extensions are usually noted in parentheses if they differ from the file format name or abbreviation.
 Many operating systems do not limit filenames to one extension shorter than 4 characters, as was common with some operating systems that supported the File Allocation Table (FAT) file system.
 Examples of operating systems that do not impose this limit include Unix-like systems, and Microsoft Windows NT, 95, 98, and Me which have no three character limit on extensions for 32-bit or 64-bit applications on file systems other than pre-Windows 95 and Windows NT 3.5 versions of the FAT file system.
 Some filenames are given extensions longer than three characters.
RIS is a standardized tag format developed by Research Information Systems, Incorporated (the format name refers to the company) to enable citation programs to exchange data.

Question: What is the format name that Viscosity can work with that was developed by Steve Wilhite?
Answer: Graphics Interchange Format
