Dear Online Advertising Industry, I have noticed recently that you have become very passionate about transparency. Mark Zuckerberg, you have said you want to bring Facebook to an " even higher standard of transparency." Google, you have issued a "Transparency Report" IAB - you've said "Transparency Is The Key To Programmatic Success" Marc Pritchard of P&G, you have given an "...impassioned speech on transparency." Keith Weed of Unilever, you have "...demand(ed) more transparency" from digital media. Sir Martin Sorrell of WPP, you have said "it’s important to be transparent." 4As - you have issued the " 4A’s Transparency Guiding Principles of Conduct " ANA - you even created and celebrated Transparency Day! (Was there a parade? Did you have a Transparency Eve party?) It seems like transparency is all the rage in the online ad world. Or maybe it would be more accurate to say that talking about transparency...
