Bulk edit tools added to the AdWords web interface for keywords, ads, ad groups and campaigns

The Edit control became a menu of bulk actions so that bids, statuses, ad text, URLs and other settings can be changed for many items at once directly in the browser, with a preview before the changes are applied. The tools were rolling out to all advertisers in the weeks after the announcement.

The Screaming Frog timeline lists 4 December 2012 as the date bulk edits reached all users; Google's announcement is dated 8 November 2012, which is used here.
