OK, I just read today's TurnSignalsOnALandRaider and it got me thinking: How would advertising look in 40K? Probably the ecclesiarchy and administratum demand that X% of every pannel be dedicated to Imperial cult propaganda...
Things like:
"Lucky Strike - supporting the troops since M02"

I really doubt those below would survive for long...
Vid of people worshipping chaos in the living room. Inquisitors bash the door in, and are greeted by a smiling inhabitant. "Let me guess, sale at Ikea?"
An Adeptus Mechanicus digging himself from under a heap of G-strings: "Axe effect"
A dead Hive Tyrant with an insecticide can next to it.
