message: Shelby Electric Company as originator of the "Mazda" trademark? Needs a citation. --Wtshymanski (talk)
: OK, a museum Web site  gives the Shelby version of the story. However this site  (Ed Covington) claims that Frederick P. Fish was a lawyer representing GE in 1893.  But the Shelby museum says that John Chamberlain Fish started the Mazda Lamp Company in 1897.  Covington says the Mazda trademark was suggested by (F.) Fish and registered (No. 77779) by GE in early 1910. All the other places I've looked don't mention Shelby at all and say GE started selling "Mazda" labelled lamps in 1909. Needs more facts. --Wtshymanski (talk) 19:36, 27 January 2012 (UTC)
replies: text: Frederick Samuel Fish doesn't have him working for GE. But he's a lawyer and he lived around the right time. --Wtshymanski (talk) 19:38, 27 January 2012 (UTC)
replies: text: Who were the other Mazda companies?  One book says only GE and Westinghouse -that can't be all, there's more Mazda licensees listed on the Covington site.  An advertisement in the IEEE PES magazine says that "30 utilities" were supplying Mazda bulbs, but an electric utility is not a bulb manufacturer. --Wtshymanski (talk) 16:35, 29 January 2012 (UTC)
replies: text: Nor is a supplier necessarily a manufacturer. I did some searching but wasn't able to pin down anything solid. Is there an online trademark search that goes back that far? --Guy Macon (talk) 19:53, 29 January 2012 (UTC)
replies: text:  Well, yes, the 77779 trademark on the US Patent and Trademarks site does show it registered to GE in 1910, and GE claimed use in 1909. If anyone was using that mark before, they didn't register it. --Wtshymanski (talk) 20:49, 29 January 2012 (UTC)

thread_title: Needs a reference

message: Mazda was a trademark of light bulbs sold by AEI Industries (later Thorn-AEI) in the United Kingdom (under license?).  Like most light bulb manufacturers, AEI also got into the business of selling valves (vacuum tubes) and later cathode ray tubes, most of which under the Mazda name (among others).  If you bought a television set in the UK in the 1960's and the valves and CRT were not manufactured by Mullard then they would almost certainly have been the Mazda brand. 86.157.172.34 (talk) 16:27, 10 January 2013 (UTC)

thread_title:  More to Mazda than the article suggests 

message: I note that the date for the registration of the Mazda brand is given as 1909 (though no reference to support it).  I have in my possession a Mazda publication that claims that the company produced the World's first ever valve (vacuum tube) to go on commercial sale (Under the unimaginative type designation of simply 'A' - and described as a Fleming oscillation valve (diode to you)).  They claim that they did this in 1906.  Since the job of manufacturing early valves was undertaken by pre-existing electric lamp munufacturers (as the production technology was identical), this suggests that the company Mazda way well have existed before 1906.  
I have just uncovered evidence that the name Mazda was applied to tungsten lamps in 1909.  However the name was used for carbon filament lamps in the 1890's, even in conjunction with Edison's name as 'Edison-Mazda'  86.181.52.76 (talk) 17:29, 12 September 2013 (UTC)
