Jack Ryan domain name registrations make sense? — Do these

Amazon Prime just released a fresh Prime Original series Tom Clancy’s Jack Ryan. Amazon has been promoting this on Prime Video for months.

Yesterday, the firm registered these domain names:

jack-ryan-tv.com
jack-ryanseries.com
jack-ryantheseries.com
jack-ryantv.com
jackryan-tv.com
jackryantv.com
tom-clancys-jack-ryan.com
tomclancys-jackryan-tv.com
tomclancys-jackryanseries.com
tomclancys-jackryantheseries.com
tomclancys-jackryantv.com
tomclancysjackryan-tv.com
tomclancysjackryantv.com
tomclanys-jackryan.com

Amazon always makes a slew of defensive domain name registrations when it launches a fresh product. But some of these seem way over the top, counting the typo tomclanys-jackryan.com.

Also, with Amazon promoting this fresh series for a long time, why register these domains just now?
