Roy, you previously stated, "I never really understood why " and I gave a response to 'why'. I just did a bit of research, and it gives the history behind the 'why'. http://www.takegreatpictures.com …maging-by-jon-sienkiewicz
"Lester Bogen, a graduate of Cornell University, was a man of many talents, including proficiency as a photographer and writer. He acquired a small company that distributed darkroom supplies and photographic accessories in 1959 and founded Bogen Photo. In 1970, at the photographic industry’s premier biennial trade show in Cologne, Germany, Lester Bogen met Lino Manfrotto and the perfect storm of innovative camera support accessories and studio equipment was formed.
"Manfrotto, whose background included a stint as a photojournalist in Northern Italy, had developed an innovative line of lighting stands. After receiving strong, positive responses from professional photographers at a seminar in Switzerland in 1969, he decided to display his wares in Cologne at Photokina. Bogen recognized the U.S. sales potential and convinced Manfrotto to develop a separate manufacturing company. (Until that time, Manfrotto had been producing the equipment in a workshop he’d set up in his father’s garage in Bassano del Grappa, north of Rome.) That was the birth of Lino Manfrotto & Co. SPA.
"The history of Bogen and Manfrotto remains permanently intertwined even today. Lester Bogen insisted that Manfrotto manufacture a line of camera tripods. The first two models were the 028-TRIMAN (known as the 3046 here in the US) and the 058-TRIAUT (3051). Today, nearly 40 years later, Manfrotto produces more than a half-million camera and lighting supports each year."
Manfrotto started making light stands (I didn't know that Bogen sourced its lighting stuff from Manfrotto, too.). Bogen later was the one who caused Manfrotto to start making tripods.
Lester Bogen negotiated the sale of his company to Hasselblad before his death in 1988. Vitec purchased Manfrotto in 1989. Then Vitec purchased Bogen. In 1992 Manfrotto (parent Vitec) purchased Gitzo. In 2004, corporate parent Vitec created Bogen Imaging Ltd as a distribution arm headquartered in UK. Then In 2010, Bogen Imaging changed its name to become Manfrotto Distribution in all of its territories-Germany, France, Italy, UK, Japan and the USA.
