City AM has reached a distribution of 100,000, some 18 months after its launch.
The business and finance paper now has a total distribution of 100,640, according to official figures released by ABC.
The paper launched in September 2005 and is handed out at commuter hotspots throughout the City of London and Canary Wharf.
City AM chief executive Jens Torpe said: "Ever since launch, we've had our sights set on reaching the magic distribution of 100,000 and this figure is testament to the hard work of the team at City AM.
"We're continuing to successfully attract new readers, while retaining an existing loyal readership base and we now look forward to building on this figure and gradually growing the high quality audience to our advertisers."
