In 1971, Dick introduced the Modern Office Modules (MOM) system and significantly altered the company's direction. Sales grew to $6 million the following year. In 1976, Dick, then 33, took over for his dad as president and CEO. G.W.’s role shifted to board chairman. Under Dick's leadership, the company's name changed to Haworth. He grew the company by 400 percent over the next 20 years. The company focused exclusively on contract office furniture and sold its partition and movable-wall business to Trendway. Dick patented the first cubicle wall panels with internal wiring. The prewired panels and patents were the most innovative workplace products since open-plan offices systems. The top-selling panels, called Uni-Group, could be easily snapped together and eliminated the client's need to pay electricians to wire office spaces. In 1977, Haworth International Inc. was formed to set up foreign licenses for the manufacture and marketing of office interior systems. A year later, Haworth opened a national showroom in Chicago's Merchandise Mart.
