Hammock Inc.’s eponymous head-helper, Rex Hammock, is among the 12 “media and publishing” Nashvillians included in the 450 top business, political and civic leaders honored in the Nashville Post’s 5th annual “In Charge” list. This is the second consecutive year the list has included Rex, the eponymous.

The Post post notes that Rex was “a trailblazer in blogging (he was the first person to blog a meeting with a president, in 2004) and social media (his Twitter handle is @R)”  – which gives you an idea of how closely he follows developments in social and other kinds of media.

Rex founded Hammock in 1991 as a specialized marketing services company creating media that companies and organizations use to communicate directly with their customers or members. He also helped to found the national trade association, the Custom Content Council, of which Hammock Inc. is a founding member.
