dumber question about the last days of third party manual focus lenses

Thank you!
I got some Tamron histories in my archive, but was not aware of that most useful.page. I got their Adaptall lenses from 1991 and 1994, but now I learned that there are 4 successor models.
 
Back to the orginal question:

-) Tamron
last release in 1998, discontinuation of the range in 2006

-) Vivitar
discontinuation of the range in 2004 (to the OP)

-) Sigma
the latest catalog I got at hand is from 1996
