Share a story or a link to an interesting news article that addresses how a particular company or industry is using data to improve its business. Explain why you think this use of data is particularly compelling.
If you are not aware of any specific applications and wish to search about an industry of interest to you, be on the lookout for recent articles about "big data".
You may instead choose to draw from personal experience if you've worked for a company that uses analytics (but please make sure to not disclose confidential or proprietary information).
