A sandbox is a testing environment that isolates untested code changes and outright experimentation from the production environment or repository, in the context of software development including Web development and revision control.
Advanced Programming in the Unix Environment is a computer programming book by W. Richard Stevens describing the application programming interface of the UNIX family of operating systems.
 The book illustrates UNIX application programming in the C programming language.
Scott Seebass began his career in the computer networking industry at the age of 20 when he co-authored the "Unix System Administration Handbook" with Evi Nemeth, Trent R. Hein and Garth Snyder in 1989, now in its third edition.
 This book is a primary tutorial for Unix as it covers FreeBSD, HP-UX, Linux, and Solaris.
 Mr. Seebass went on to work at Interactive Systems and MT Xinu, where he focused on developing MORE/bsd, a commercial version of Unix.
 Recognizing the possibilities of Unix programming, Seebass co-founded Xinet in 1991, a digital asset management company.
 Xinet was acquired by North Plains Systems in April 2012.
 Seebass holds degrees in Computer Science and Statistics from University of California, Berkeley.
Wang Laboratories was a computer company founded in 1951, by An Wang and G. Y. Chu.
 The company was successively headquartered in Cambridge, Massachusetts (1954–1963), Tewksbury, Massachusetts (1963–1976), and finally in Lowell, Massachusetts (1976–1997).
 At its peak in the 1980s, Wang Laboratories had annual revenues of $3 billion and employed over 33,000 people.
 It was one of the leading companies during the time of the Massachusetts Miracle.
Degrémont is a company specializing in the production of drinking water, and in the treatment of sewage and sludge.
 After starting as a family business in France in 1939, it has since become a subsidiary of Suez Environment, employing 4,600 people in 70 countries, and generating annual revenues of €1.520 billion (2010 figures).
Computer Consoles Inc. or CCI was a telephony and computer company located in Rochester, New York, United States, which did business first as a private, and then ultimately a public company from 1968 to 1990.
 CCI provided worldwide telephone companies with Directory Assistance (DA) equipment and other systems to automate various operator and telephony services, and later sold a line of 68k-based Unix computers and the Power 6/32 Unix supermini.
Eclipse is an integrated development environment (IDE) used in computer programming, and is the most widely used Java IDE.
 It contains a base workspace and an extensible plug-in system for customizing the environment.
 Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including Ada, ABAP, C, C++, C#, COBOL, D, Fortran, Haskell, JavaScript, Julia, Lasso, Lua, NATURAL, Perl, PHP, Prolog, Python, R, Ruby (including Ruby on Rails framework), Rust, Scala, Clojure, Groovy, Scheme, and Erlang.
 It can also be used to develop documents with LaTeX (via a TeXlipse plug-in) and packages for the software Mathematica.
 Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++, and Eclipse PDT for PHP, among others.
COBOL ReSource is a Wang VS COBOL development and production environment for Unix.
 A product of Getronics (formerly Wang Laboratories, Inc.), COBOL ReSource was first released in 1993 as a tool to replatform and run Wang VS COBOL applications in Unix.
 It was updated and rereleased in 1995 and its maintenance and ongoing development outsourced to SRDI in the late 1990s.
Kitchen Table International was a fictitious computer company created as a faux amalgam of Radio Shack, Apple Inc., Commodore Business Machines, and other organizations of the time, and was the subject of one of the earliest regular computer humor columns, appearing in Wayne Green’s 80 Micro magazine from January 1980 through July, 1983.
 Invented by computer journalist David D. Busch, and billed as the “world’s leading supplier of fictitious hardware, software, firmware, and limpware” each month a new “innovation” was introduced that poked fun at the infant personal computer industry.
 These included a “black phosphor” computer monitor, and a programming language with all the worst features of BASIC and COBOL, called BASBOL.
 The fictional company’s flagship product was the TLS-8E, a computer which was sold with a factory-applied coating of oxidation on its peripheral edge card connectors (“to protect them from electricity”), a 5-inch “sloppy” disk drive, and a keyboard that eschewed the familiar QWERTY array for a 16-key matrix that included a TBA (To Be Announced) key.
VSE Corporation is a diversified technical services company formed in 1959.
 VSE employs over 2,700 people.
 Its 2008 and 2009 annual revenues surpassed $1 billion; 2007 revenues were reported at $653 million.
 In 2010 VSE Corporation was named the #1 Growth Company (over $500 million) by the Association for Capital Growth in the DC area; Ranked #1 Federal Contractor (small) by Government Executive magazine; #1 Climbing Company by Washington Post 2009; 6th Hottest Company in America by Business Week in 2008; ranked #4 on the 2007 Forbes 200 Best Small Companies in America list of U.S. companies.

Question: What were the annual revenues of the computer company for which COBOL ReSource is a development and production environment for Unix?
Answer: $3 billion
