[78-L] Inquiry: Demise of the 10" Long Play

[Martin Fisher]

Hi Guys,

The following question has been asked by a teaching colleague:

"When exactly did record companies/labels stop issuing 10 inch LPs in favor of the 12 inch format and why was the change made."

I realize that there are a myriad of reasons as long as a Santa list and that the switch was not simultaneous for all labels and size of the issued disc also depended on the amount of material that was to be issued and both sizes were issued by the same label depending on this criteria.

He's really looking for information from printed sources so that's the first priority........but........in lieu of printed documentation he may be satisfied with expert testimony by an "authority" on the subject so here may be your chance to shine.

Thanks for any help!  :)
