How effective is social media for event promotions?

Hi, I am currently researching the effectiveness of social media as a marketing tool for event promotion for my dissertation. I would be incredibly grateful if you could spare 5 minutes of your time to fill out my short questionnaire. I believe my study will provide some great insight in to current event promotion strategies and be able to create positive support and development opportunities for the use of social media in the event industry.
