Could mean all kinds of things

I draw your attention to the following sentence in a Guardian article, featuring an alternative use of the word hoarding:

Dame Judi Dench has come to the defence of the drama school where she learned her Oscar-winning craft.

The London borough of Camden has banned two advertising hoardings outside the Royal Central School of Speech and Drama on supposedly aesthetic grounds.

The Central says that it receives up to £150,000 a year from advertisers using the sites, which it donates to theatre charities involving thousands of young people nationwide, and that there have been no complaints since they went up 27 years ago. An appeal to the secretary of state will be heard on Tuesday.

Next up: a discussion of advertising row.
