Den wiring

I bought a new PC and replaced an outlet for it in my den. I realized that all the outlets in the den only have 2 wires going to them and I believe the homerun is in the ceiling light box.

Is this abnormal?

Older wiring was not grounded. Depending on the wiring method you may be able to ground the receptacle. What is the wiring method?

The outlets are grounded, that's not my question. I was wondering about the junction being in a ceiling box instead of fed thru the outlet boxes.

Nothing unusual at all for older wiring. Newer wiring is run in a different manner.

How?
They are mechanically grounded thru the metal conduit system in my home.

What's the downside of having the homerun in the ceiling? Harder to service comes to mind.

Is it hard pipe conduit such as EMT or threaded rigid heavywall conduit or is it flexible metallic cable such as BX or AC cable? Homes wired with conduit are very rare except for in a few areas of the country.

Its all bonded rigid and emt. Im in northern Indiana where I assume builders were influenced by the conduit rules of Chicagoland.

So why is branching out from the ceiling considered old practice?

Methodology just changed. I don't know the reason.

Once upon a time when electric was new and intended for lighting there were no receptacles. When manufacturers came out with fans and toasters and such they had Edison base screw in plugs for light sockets. That could be inconvenient so then came two prong receptacles and plugs. The new fanged receptacles were just connected to the nearest power source, the overhead light. As time went on it became a habit even for new construction for many years.
