Glen P. Robinson was the CEO of Scientific Atlanta for 20 years, and chairman of the board for an additional eight years, until he retired from the company in 1979. Scientific Atlanta grew dramatically; it earned $3.1 million in revenue in 1962 and approximately $200 million when Robinson left. Sidney Topol served as its president from 1971–83, CEO from 1975–87, and chairman of the board from 1978-90. During his tenure, the company grew in sales to more than $600 million. During the 1970s the company developed the concept of cable/satellite connection, which, in working with HBO and transportable earth stations developed by TelePrompTer Corporation and manufactured by Scientific Atlanta, established satellite-delivered television for the cable industry.
