Bertelsmann AG, via its DirectGroup, is buying the other 50% stake of Time Warner's (NYSE: TWX) Bookspan. Bookspan owns roughly 40 book clubs, including the "Book of the Month Club." Financial terms were not disclosed.

Time Warner and Bertelsmann formed the partnership in 2000. This also includes the Doubleday Book Club and Literary Guild. Bertelsmann will reel in Bookspan into its BMG Columbia House.

BMG will now be the clear leader, with no real competitors in book, music and DVD mail order clubs in North America. This is all part of Time Warner's strategic changes after it closed Life and sold off 18 magazines earlier. It appears that even if an industry is shrinking, there at least may be some perceived value in being a virtual sole-supplier.

The most valuable thing on earth after life itself is TRUST.

Why is President Bush watching his approval rating collapse month after month -- Do you trust him? What has he done to build trust? Why are we so comfortable living with England having nuclear weapons and are panic-stricken by Iran's having them -- do you trust them? What have they done to build trust?

What was the cause of Adam & Eve's being banished from the garden of Eden? A breach of trust. Right from the start, up until this very moment it is trust that creates brotherhood between peoples and also builds strong brands. Trust that allows a temporary leap of faith until the facts are known and it is trust that positions the market place for "just-in-time" manufacturing and without which the process would come to a swift and grinding halt.

Johnson & Johnson did all the right things way back when they had the now-historic Tylenol tampering scare to contend with and they wisely focused their attention on maintaining trust at all costs. Enron did all the wrong things. Arthur Anderson drowned in a sea of mistrust flowing from their own questionable ethics and we witnessed a very valuable enterprise rapidly collapse. In my architecture practice I have lectured on this subject constantly to everyone who would listen; staff, clients, consultants, public officials etc. Anything that builds trust is a good thing, anything that reduces trust is a bad thing!
