Looking at the Channel 4 closet swap reminded me of this campaign that Marks and Spencer launched a little while ago called shwopping.
The basic idea is that everytime you go in to buy a new piece of clothing you donate one at the same time.
M&S will then give this piece of clothing to Oxfam.
To launch the event, Marks and Spencer placed thousands of pieces of clothes all around the Truman Brewery and the area surrounding it in East London.
Here are some snaps of the event.
There is also a nice little introductory video on the website here:

And here is the TV advert:
Like with the Closet Swap campaign, an important part is the interactivity; using the associated Facebook application, you can earn point and special awards, vote on other peoples clothes as to whether they should shwop or not and enter yourself into prize draws.
There are also leader boards - one for the person with the highest number of shwops and one for the store with the highest amount of clothes.
After you shwop you are given a code for your mobile phone which, like the closet swap, means the campaign is with you wherever you go.
Another thing I noticed form the campaign was the mentioning of the history and future of a product - something which I could think about with the products I have been looking into.
