From Kathmandou international airport, my trip continued by
bus to Chitwan Natural Park about 5 hours drive from
Kathmandou; then from Chitwan we went to Pokhara (another 4
hours drive) where we were stuck for 4 days as we could not make our next move
and we ended up to drive to Kathmandou before flying back to Beijing.
We did spend some time on the orad mountains where we saw a lot of ads
actually, PAINT ADS. Indeed, like what we can find in the
countryside of China or I believe in many areas less developed, the best way
for advertisers to have space is to rent a space directly on Walls of buildings
or home or even directly on the mountain road stone protection to paint your
ad.
For the buildings or personal homes, I believe the media company may
directly discuss with the owner and pay them a yearly rent and then re-sell the
location but I am not sure.
Seeing that the country is not that huge and cities have a reasonable size,
I also thought that maybe the brands have staff who can directly go discuss
with the owners to rent the space on their buildings or home.
Unfortunately, I was too sleepy on the bus to have the chance to take pictures
of those ads but I think my friend might have some, I'll post them in the
coming days. but for now, I can share with you the painted ads that you can see
inside the city.
Here you can see the Total logo painted on a store
that looks like a lubricant store:

For the shops, we can ask ourselves the same thing. In a typical Nepalese
street, you will have the shopes entrance directly on the streets and the
entrances are all Steel doors (see picture_ i am not sure of the english word
for this kind of thing). On the top of each door, you can find an AD panel that
may or may have not something to do with what the shop actually
sells.

Here you can see Castrol as well which is a big
outdoor advertiser in Nepal.
