Ninety-One Years Ago at Edison • Highlights from the Spring–Summer 1928 Catalog Supplements
By mid-1928, development of standard lateral-cut discs was well under way at Edison, although no hint of them will be found in these catalogs. (The company began circulating some experimental sample pressings in the spring of 1928, but the new lateral-cut “Needle Types” would not start shipping to dealers until July 1929).
Although by now the company had worked out the kinks in its electrical recordings, which employed General Electric equipment (Edison had no hand in developing the process, contrary to some ad copy), the records were still vertically cut, a format for which little demand remained. Many of these 1928 releases sold only a few thousand copies, if that.
