CBS and Paramount Pictures have officially named the alternate universe after 7 years of it being known as the “JJ-Verse” or “Abramsverse” to the “Kelvin Timeline”. The name was revealed for the first time by Star Trek Online lead designer Al Rivera on Twitter.
FYI, “Kelvin Timeline” is the official name for that universe timeline according to CBS.

The timeline was altered when Nero traveled back in time and destroyed the USS Kelvin.
