Many bitmap framebuffers (printers, old displays) were lsb2msb — the order depended on the whims of the implementer.
Also, I understand that FAX is commonly sent in reverse bit order (lsb2msb) which differs from the normal convention for today's CPUs. CPUs were not involved when FAX was first invented. Later, when the CPU was added, the CPU was weak and puny so the data was stored in the order presented.
