WAVEMASTER (#121)

[Cellfish]

I've been more interested in cataloguing my music by publisher lately, because it helps identify originals, re-prints, etc. Just curious, why is every reference to this publisher one word "WAVEMASTER" on VGMdb, when the logo and all their albums (that I've seen) have a space in the name (Wave Master). Have they done it both ways over time? I know I've seen many slight variations in other publishers' names.

Also, their official website URL has a dash in it (wave-master.com), and is typed out on their website with a space:
"© 2015 WAVE MASTER INC. All Rights Reserved."
