I’ve always been too lazy to look up the reason for the change of name. Today I did: https://www.linux.com/news/ethereal-changes-name-wireshark/

TLDR: Authors previous employer trademarked the Ethereal name on the Authors behalf, the author moved jobs and couldn’t negotiate the transfer to him - thus Wireshark was born.

Very cool. Wireshark is one of those things that has been around for so long it’s easy to take for granted, so it is nice to be reminded that it took a huge cooperative effort over more than two decades to get where it is. One of the really great examples of what open source can do.
