Just wondering if the 25,000-mile interval actually appears on the bottle labels anywhere, or if that's just in their ad copy.

The Series 2000 0w30 TSO has 35,000 miles or 1 year along with the 12500 mile filter change info.
Keep in mind this is for mechanically sound engines driven under normal circumstances. Short trips, dusty conditions, towing, racing, etc... will shorten that interval.
Also refer to the Oil Change Interval Chart that is in PDF located here:

Lastly, you can extended drain intervals indefinately by using oil analysis, bypass filtration.
