DOC files were most likely created by MS Word prior to 2007 (after which DOCX became the default format extension). However, the DOC extension may result from a variety of sources, including WordPerfect. Even when created by MS Word, there are four distinct variations of DOC files depending on the version of Word and the OS platform.
