GeoNames.org or OSM will give you natural places ("New York", "River Thames", etc). Commercial places ("McDonalds", "Cafes", etc) are primarily proprietary databases.
As a reference, Apple maps sources its commercial places data from a combination of: TomTom, Automotive Navigation Data, Getchee, Hexagon AB, IGN, Increment P, Intermap Technologies, LeadDog, MDA Information Systems, OpenStreetMap, and Waze.
