MARANTZ Timeline 1950-2003 - Chronological History of Marantz Company
The following timeline comes from a Stereo Sound special edition dedicated to Marantz published in 2003. The book was meant to be distributed to key people in the industry but not to be available for sale... The quality and thoroughness of it are one thing, the other is that, for once, this Stereo Sound publication saw an english edition !
I'm sure the Stereo Sound editorial dept. won't mind me bringing this online as it will help put an end to the many misconceptions and erroneous assumptions so far present online, especially the Philips/DynaScan/Superscope split ownerships.
I will try later on to bring several other specific features of this sadly unavailable book and will manage to bring the many tidbits of info throughout the pages of TVK.
In the meantime... enjoy !
