On the day that the Mayor of London announced the start of the Night Overground, TfL announced an expansion of video advertising screens in the London Underground.

The series of giant advertising screens are coming to tube stations following an upgrade of the older video screens that were trialed in some stations.

The displays, which are 4.5m x 2.4m in size, will be located at 15 tube stations within Zone 1 and Zone 2.

The launch stations for the week commencing this week:

Camden Town

Piccadilly Circus

Holborn

Oxford Circus

Liverpool Street

Exterion Media, which handles the advertising sales says that the screens will serve 5.5 million adverts per fortnight and that its screens are a “positive disruption to the everyday commute.”

By the end of January, there will be 60 of these displays across 16 stations.

Not that anyone would ever waste time on it, but there’s a fun little tool that lets you see a video of what your advert could look like on buses or in tube stations.
