London's Independent Television channel had a brief item about the Pop-Up Christmas Post Office in Camden Market mentioned here.
The video clip is only 20 seconds - the actual broadcast must have been longer? - and it may not be online for long, but you can see the report here.
Readers outside the United Kingdom may not be able to view this footage. It is good to see that this initiative is getting exposure in the general media.
