Dominica
DOMINICA is a small island in the Caribbean, not to be confused with Dominican Republic.
DOCTOR WHO IN DOMINICA
BBC Records
In The Eighties - THE LOST CHAPTERS, a sale of "(7)" stories is recorded for Dominica.
However, it's not clear if this is a reference to Dominica, the Commonwealth island nation of that name, or an abbreviation for Dominican Republic, a much larger, Spanish-speaking nation, also in the Caribbean, which had apparently screened William Hartnell stories back in the late 1960s.
Dominica does not have its own television service, but does have three cable television companies, such as Marpin TV, and therefore might not have been one of the nine Caribbean countries to which the series had been sold in 1985.
One Dominican newspaper was checked, but there were no TV listings.
