Think C, and later Symantec C++, featured a class library and framework for Mac programming called the Think Class Library (TCL), which was used extensively for Macintosh application development. The long-awaited version 8 brought support for compiling to PowerPC. After version 6, the OOP facilities were expanded to a full C++ implementation, and the product was rebranded Symantec C++ starting version 7, then under development by different authors. Versions 3 and later were essentially a subset of C++ and supported basic object-oriented programming (OOP) concepts such as single inheritance, and extensions to the C standard that conformed more closely to the needs of Mac OS programming. The firm was later acquired by Symantec Corporation and the product continued to be developed by the original author, Michael Kahl. THINK was founded by Andrew Singer, Frank Sinton & Mel Conway. Think C (stylized as THINK C formerly Lightspeed C) is an extension of the C programming language for the classic Mac OS developed by Think Technologies, released first in mid-1986.
