Years ago, agencies and advertisers signed a Charter, which lays down 7 rules for agency competition. Today more and more advertisers are ignoring it.

To remind advertisers of their commitment, agencies joined forces.For 1 week, 24 agencies went into Virtual Strike by replacing their website with a part of an open letter. To read the entire letter, you had to click from one agency to the other. The more agencies joined, the more parts the letter was split into and the bigger the chain was.No matter where you started, you always began at the top of the letter.
