CVB, DMO, DMC: What's the Difference?

We live in a world of confusing acronyms, especially in the meeting planning and hospitality industries. For instance, if you’re an NRA member do you subscribe to the belief that everyone has the right to bear arms (National Rifle Association), or are you concerned with health regulations in public eating facilities (National Restaurant Association)? If you google USTAare you looking for information on sports programs for youngsters (United States Tennis Association) or are you researching the impact of tourism on the national economy (U.S. Travel Association)? If you want to work with a destination expert to find the perfect fit for your next meeting do you contact a CVB, DMO or DMC?
