Snippet from Chris Tacy's blog today about Net Promoter Score in the advertising business. Useful NPS statistic - the average for the category: 21%. "Seeing the gap in perception between agencies and clients on the value of an agency is shocking. When 90% of Agency Execs say their firms are "well-equipped to help deal with changes in Internet Advertising" while less than 50% of Clients feel the same way... or seeing an even greater gap when the same question is asked about Consumer-generated media... the picture starts to get painfully clear. And seeing a client-generated aggregate Net Promoter score for Agencies of 21% is kind of horrifying. "
