Presenting around the world I just finished a seminar presentation to Monash University while sitting in Redmond -- the slides were presented using PowerPoint 2013 via Office Presentation Service a free way to control your presentation to anyone in the world.  While the PowerPoint broadcast feature has been included in previous versions of PowerPoint it's really amazing how easy it is to use -- all the viewer needs is a browser, so it works on almost any device/smartphone. Start an online meeting from PowerPoint Now you've got several ways to share a PowerPoint presentation over the Web. You can send out a link to the slides, or start a full-on Lync meeting that displays the deck with audio and IM. Your audience can join you from anywhere, on any device using Lync or the Office Presentation Service.
