Whilst they were a great idea at the time, it has to be said, the XTP (Cross Track Projection) format has had a relatively sketchy existence since (the very dealyed) launch. The actual format is compromised and the quality questionable .. especially in light of progressive digital technology and the high quality formats now featuring in and around most under and overground stations.
That said, it seems criminal that such formats (unless the projector is broken of course) should not be used at all.
Surely, if they don't have paid for advertisers running campaigns - then pro bono campaigns should run instead.
There are plenty of charities that don't have enough funding to advertise at all, so giving them the opportunity to reach high footfall London audiences on busy commuter Underground platforms is surely worth consideration.
