Google+ has had pages for businesses for a while, and there was an obvious overlap between that and Google Places.

As of today, Google Places pages have been entirely replaced by new Google+ Local pages. As of this morning roughly 80 million Google Place pages worldwide have been automatically converted into 80 million Google+ Local pages, according to Google’s Marissa Mayer. It’s a dramatic change (for the better) though it will undoubtedly disorient some users and business owners.

Here’s a brief overview of what’s new and what’s changing:

• The integration of Google+ Local pages across Google properties (search, Maps, mobile)
• Integration of a circles filter to find reviews/recommendations from friends/family/colleagues

The integration does not appear to be complete, as you can’t administer your places page information from inside Google+ yet. The interface for the back end is still pretty much the same.
