There are many definitions of power, but the most useful one is the ability to produce an effect with one's actions and to induce third parties to act in response to them. This ability is on full display among the individuals on PRWeek's 2011 Power List. This year, for the first time, we have increased the list to 50 people in order to reflect the growing influence of client and agency communicators and the wide variety of constituencies into which they permeate.
The list is headed by the top communications person at the world's largest retailer, Walmart's Leslie Dach. He has certainly had a busy year, especially linking up with first lady Michelle Obama on health initiatives. Every such compilation is based on opinion and we don't expect everyone to agree with us, so please let us know who you believe should have been included or left out.
This month's issue features several powerful individuals who didn't make the list. Our Newsmaker, ITT's Angela Buonocore, talks us through the strategic challenges of splitting a corporate conglomerate into three separate public companies.
High-profile business reporter and author Maria Bartiromo tells how she established herself in the predominantly male environment of the New York Stock Exchange by exhibiting good old-fashioned journalistic chutzpah.
And New York City Mayor Michael Bloomberg explains the communications thinking behind activities to mark the 10th anniversary of the World Trade Center attacks, as his office tries to find the right balance between remembering the victims and encouraging tourists to visit the site in Lower Manhattan.
It's a powerful issue full of powerful communicators. I hope you enjoy it.
