Can you help me find examples of social media being used to promote film festivals and/or award shows?

I’ve been Googling away but this is something that’s not necessarily easy to find with a search – I’m looking for uses of social media by large appeal entertainment events like film festivals and award shows. i.e. From a conventional blog to even If the Emmy’s had Twitter, or a YouTube channel for one of those suites where they give celebrities things, etc.
