The document discusses the use of social media in business-to-business environments for travel companies. It outlines various ways social media can be used, including providing travel information, customer service, experience sharing, company communities, and new collaborative services. The presentation then provides a case study of how Société Générale uses a social network called SG Communities, including a travel group with 500 members that shares news, information, and forums. Key takeaways are that social media use is growing due to trends like mobility, blurring of personal/professional lives, and the need for instant information and interaction, but companies should consider their objectives, resources, and traveler needs when utilizing these tools.
