Just a look into one of the many PR campaigns that caught my eye. I remembered this from long ago and googled it. Pretty difficult to find actually.
This is a little experiment done to promote ST701, which is an e-marketplace by SPH's CATS Classified. A beauty queen was invited to live in a glass house for a week. She slept, ate, 'shat' and did not leave her glass house for that whole duration. The aim was to show the public (through 'transparency' of the glass house) that one did not need to leave the house as long as you have access to ST701. I thought it was a good concept. Cool idea, with good publicity, especially since it was in the heart of Central Business District (CBD). But the competition (The Ultimate Date) was a tad cheesy.
