The Global Public Relations Summit will attract senior communications professionals recognized in The Holmes Report's Influence 100 list of the 100 most important in-house communicators in the world - the 2012 edition of the report will be unveiled at the event.

The role of the senior public relations professional within major corporations— and other institutions that face intense public and media scrutiny—has grown more complex and challenging in recent years. The rise of social media has empowered stakeholders and spawned new threats to corporate reputation, and smart CEOs have come to realize that a trusted communications advisor is essential to their success.

The 100 senior corporate communicators profiled in the Influence 100 are senior counselors to some of the most powerful CEOs in the world. In compiling this list, the Holmes Report relied on external nominations along with its own editorial research, basing all decisions on discrete set of criteria.
