The car you drive probably has close to a dozen PowerPC chips in it.
MOT is a $20 billion a year electronics company, and most of those
chips have PowerPC hidden in them.
The semiconductor business of MOT was transferred to Freescale
Semiconductor in 2004, which is a 3.5B company.
MOT still owns license free copies of all those PowerPC cores,
and uses those cores in most of their products, regardless of
who fabs the chips. So the total is (20B + 3.5B) / percent CPU.
Even if you round down to 3 billion, second place ARM is .6 billion,
or .2 billion before Apple bestowed some king maker grace on ARM.
PowerPC dominates because of AltiVec and the bitfield extract and
other cool useful instructions that give good performance and good
inner loop code density.
I would say PowerPC is big in the embedded market due to the
good spectrum of different chips that have rich set of peripherials.
The processor itself is not that critical, all the support logic around
is (memory controllers,i2c, ethernet, accelerators, flash, usb etc.).
This is where Intel for example has problems with their Atom.
