Maybe “pull” was the wrong word. However, looking at https://wiki.openstreetmap.org/wiki/History_of_OpenStreetMap I see:
- 4th December 2006 – Yahoo! aerial imagery sketching allowed…
- September 2007 – TIGER data import for the US started
- 20th September 2007 – AND Data for The Netherlands imported
- 1st April 2010 – Ordnance Survey Opendata releases.
- 30th November 2010 – Use of Bing vertical aerial imagery allowed
And on https://wiki.openstreetmap.org/wiki/Contributors it shows well over a hundred counties/regions with hundreds(?) of non-user data sources/sets that are used by OSM to maintain the map.
Edit: clarity.
