In the remainder of the 1960s, Teledyne acquired some 90 more companies. A number of these businesses were in consumer products, such as Water Pik, Acoustic Research with high-fidelity speakers, and Olson Electronics that operated retail stores across America. Packard Bell Corporation had both consumer and government sales in computers and television receivers. A number of electronic product lines and smaller acquisitions were consolidated in Teledyne Electronics and Teledyne Microelectronic Technologies. Two acquired firms, Geophysical Exploration and Geotronics, brought Teledyne into off-shore drilling and earth-science instrumentation fields. Twenty-one acquired companies were in the metals business, including Wah Chang and Cast Products, and this led to the acquisition of firms producing industrial machines and machine tools. Other diverse acquisitions included Monarch Rubber, Sewart Seacraft, Isotopes, Radar Relays, Getz Dental, and the agreement with Subaru to market Wisconsin engines.
