C-COR
C-COR (former NASDAQ symbol CCBL) is a communication services company incorporated in 1953 and based in State College, Pennsylvania. The corporation is best known for creating video transport systems. In 1965, C-COR introduced the use of integrated circuits in amplifiers used on utility poles and in 1969 was the first to use heat fins on amplifiers. In 1991, C-COR was the first to introduce a 1 GHz amplifier.
Since the 1990s, C-COR's business focus has moved from hardware amplifiers to communications service and software such as video on demand and cable television advertising insertion. In 2005, C-COR purchased five software companies: nCUBE, Optinel Systems, Stargus, Alopa Networks, and Lantern Communications. In 2006, as part of a 225 person layoff, C-COR closed the Sunnyvale, California home of acquired Alopa Networks and Lantern Communications.[1] C-COR was sold to ARRIS in late 2007.
