Case study ideas

I am on the look at for case study ideas but I'm a bit confused, rather stomped. I look at your example and kinda get the idea now. We have to find something negative or positive in the news that affects a company. Like for example TI products are everywhere now including medical instruments. Or that some organization has decided to donate money to build something good for the community. Once I pick a top I know I will have to research to see what other companies or organizations have done the same thing in order to help my hypothetical company make the best decisions based on facts that we have from the past. Im a little concerned but have decided to give this 110% of my mental effort.
