In the days before the Internet, getting out the news of the next MWS was slow and expensive. Printed booklets and purchased mailing lists.
The quickest form of communication was the telephone. So, for 1985 and beyond, we purchased 800 numbers from Southern Bell.
For 1985 it was 1-800-Miami-85.
Phone inquiries and registrations handled very quickly.
This continued until 1988, when Nature joined us via its Bio/Technology magazine. Tons of free ads in it.
No more need for Southern Bell.
And the 1988 MWS was, and remains, the largest on record.
