People do not update their presentation decks that often, and as a result, case examples or data that was really cutting edge 6 months ago, can quickly become stale, or even incorrect. Putting up a slide with Stuxnet, the $1 Shave Club, the Gig Economy, mobile first, can flick a switch in the mind of a clued up audience to stop paying attention or worse, feeling offended.
Usually when examples hit mainstream news sources, it is not going to wow your audience anymore. Keep your presentation fresh, with insights and data that only you can provide (and are allowed to share): meetings with customers, discussions with portfolio companies, niche scientific and technical publications, access to different countries, languages.
