How does the organization that you work (I work for AT&T) for use the Internet to promote itself or connect with those it serves?

Businesses have scrambled in recent years to use the Internet to promote their products and services, deliver support and connect with customers. How does the organization that you work (I work for AT&T) for use the Internet to promote itself or connect with those it serves?
• Does your organization have a website?
• Use social media?
• Offer online chat?
