I run this YT channle https://www.youtube.com/channel/UCXqNBLRoF81JDK7IDsK6EgQ I have listened to thousand of hours of commercial on VHS tapes. This is what is guiding my guess. This stuff was so disposable and it may have never even been used in a commercial. This book is a good read on this type of topic. Highly recommended https://www.goodreads.com/book/show/501880.Who_Killed_the_Jingle_How_a_Unique_American_Art_Form_Disappeared
