Monster Cable Products (Monster) was founded in San Francisco in 1978 by engineer Noel Lee.
The company is based today in Brisbane, CA, and has additional offices in Ennis (Ireland), London, and Hong Kong with about 650 employees, most of them in the US headquarters. The company is privately held, hence it does not publish its sales figures; however, industry sources estimate its annual revenue to be around US$500 million. Monster Cable Products, Inc. is currently incorporated in California.
In recent years, faced with increasing competition and to reduce costs, the company has outsourced many of its production lines
