Grunt Work: Rivers, Witten Among NFL Players Involved In New Social Media Channel

A group of 21 NFL players including Chargers QB Philip Rivers and Cowboys TE Jason Witten has partnered with N.C.-based startup online outfit Gridiron Ventures to create Gridiron Grunts, a new social media channel in which players will provide unfiltered audio updates, dubbed "grunts," several times per week on their various activities through a newly released iPhone application. The "grunts" can also be adapted into ringtones for users' mobile phones. The Gridiron Grunts application is being distributed for free, with premium content priced at $0.99 per month for each player "channel." An Android version of Gridiron Grunts is also under development, and Gridiron Ventures is aiming to expand the concept to other sports.
