At its peak, the chain had over 500 shops, including one at 24 Bow Street, Lisburn (pictured here in 1964), and a customer base of over two million. The company employed 3,600 technicians and 2,700 skilled installers, including some over the local area. This 1964 Belfast Telegraph advert gives some indication of the increasing popularity of television in the Lisburn area at the time.
