The Phoebus Cartel

Phillips, GE and Osram engaged in a conspiracy from 1924 to 1939 with the goal of controlling the fledgling light-bulb industry, according to a report published in Time magazine six years later. The alleged cartel set prices and suppressed competing technologies that would have produced longer-lasting and more efficient light bulbs. By the time the cabal dissolved, the industry-standard incandescent bulb was established as the dominant source of artificial light across Europe and North America. Not until the late 1990s did compact fluorescent bulbs begin to edge into the worldwide lighting market as an alternative.
