 Combs still held copyright on most of Ethereal's source code (and the rest was re-distributable under the GNU GPL), so he used the contents of the Ethereal Subversion repository as the basis for the Wireshark repository.However, he did not own the Ethereal trademark, so he changed the name to Wireshark.In 2010 Riverbed Technology purchased CACE and took over as the primary sponsor of Wireshark.
