Just about forever.

BBCC = BBC Contest

People always tend to just say BBC though

Since Jen took over. She didn't like calling them just "BBC##". Even though that's what we called them for a good forty contests.

Oh well. That's a losing battle.

She didn't like calling them that because it's grammatically unsound, and doing things just for sake of tradition is inadvisable.

Eh, they are perfectly grammatically sound. They stood for "Bionicle Building Contest".

Yeah but when the title is "Bionicle-Based Creations Contest"...............
