An advertising tool to allow companies to target tweets at specific users has been announced by Twitter. It tweets users based on their geographic location, or according to whether they access the service via phone or computer.

Previously this idea has been impractical to implement.

The feature also allows different launch dates for different countries with global brands. The tool has been tested with major advertisers such as British Airways and Coco cola, and is now open to any advertiser globally, via a newly enhanced tweet box at
