HONGKONG firm Tower Marketing is renting space on Guangzhou's 218-metre-tall broadcast and television tower.
The tower, designed specifically to take advertising displays, was completed in 1991.
It is visible by road, rail and air and, standing in a clutter-free environment, offers advertisers probably one of China's highest profile media.
Mr David Neish, marketing director of Tower Marketing, said it was ideal for corporate advertising, rather than branded goods.
''There are no other adverts in the vicinity and the tower can be seen from 360 degrees,'' he said.
''Unlike other signage in China, because of the television station, it is guaranteed electricity so the signs won't disappear inadvertently,'' he said.
Only six advertisers can buy space on the tower, by purchasing a full side of the four-sided construction or half a side.
