The service sector showed a clear increasing trend from 1997 to 2001. In 1997, the
average number of words was 88 words; the number increased to 200 words in 1999
and dramatically increased to 625 in 2001, an increase of 541percent. The properties
sector also has a clear trend with 436 words in 1997, 614 words in 1997 and 758 words
in 2001. This trend can be explained using legitimacy theory, as mentioned earlier,
which asserts that organizations continually seek to ensure that they operate within
the bounds and norms of their respective societies, that is, they attempt to ensure that
their activities are perceived by outside parties as being legitimate (Deegan, 2000).
