Field facts

No open registry defines these strings, so exchanges should publish the values they send and buyers normalize case and spelling per exchange.

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "device": {
    "make": "Samsung"
  }
}

Added in OpenRTB 2.0, and present in the latest snapshot. The table shows how each version's spec text types the field.
