123 Metro could be the name of the latest Major League Soccer franchise but it signifies a neat deal that 123Play, a service that wraps mobile games with ads free to end users, has just struck with the newspaper mavericks from Metro (they're the guys with the free newspapers; see here for UK and here for the [seeming] inventors of the concept).
I like this deal a lot as it is so natural: Metro is a very successful advertising-driven medium and it ties in extremely well with 123Play's model. Seamless, simple, very neat: anecdotally, a lot of people play games on their mobile when they have time to kill. Likewise, a lot of people read Metro when they have time to kill, namely when they commute on public transport. One challenge will of course be that there is no mobile reception in the London tube (or most other undergrounds for that matter) but the overall concept should work.
Disclosure: my company works with 123play.com (although I don't think this post will bring me front-page coverage on Metro...).
