They're not expensive. We sell them for the same price as double-butted, though they cost us a tiny
bit more. Not "necessary," but a good choice for some applications.

Yes and no. It's no more of a "marketing" term than "double butted."
The only triple butted spokes I know of are the DT Alpine III. They're
2.34/1.8/2.. These are my favorite spokes for high-stress applications: tandems, loaded touring
and the like.
Spokes have rolled threads, so the thread diameter is larger than the base diameter of the wire.
This means that hub flanges have to have holes large enough to accept the threaded parts. These
spoke holes are then slightly oversized for the elbow, and don't always support the elbow as well as
might be wished.
The 2.34 end of the Alpine III spokes is a nice snug fit in the spoke holes of any hub that's
designed for 2.0 mm spokes. I've The 1.8 middle section provides resiliency, and saves weight (these
spokes are lighter than 2.0 straight-gauge.)
