It varies.

Sometimes it is C code running in a bare bones environment, or it is
running on something like VxWorks.

Sometimes it can be truely weird stuff like FPGA configuration data. This
is becoming more common as people are just embedding mini-FPGA like blocks
in their ASIC's.

Sometimes it is assembly code assembled using an assembler the vendor
built just for the logic they designed.

Sometimes it is something else entirely - ie the intel microcode 

Pretty much everything has embedded 'firmware' of one kind or anyother. 
Sometimes you don't see it, because it is in flash or ROM'd into the chip.
Though, often it ends up in a driver primarily to save on the cost of
flash and/or to ease updating it to new versions.

The ocurrance of this is only going to increase with time..
