If you’re anything like I am, you listen to webinars with one ear, occasionally checking your computer screen if a graph or image is referenced, perhaps catching up on email or articles while the webinar is running in the background. Despite the challenges for viewers, everyone from for-profit companies like LinkedIn and Procter and Gamble to non-profits like the Red Cross and City Year to professional associations like the American Medical Association and the American Bar Association to publishers like HBR run webinars. These sessions are designed to do everything from teach particular skills or tools to discuss trends in different sectors. And they are aimed at all sorts of audiences, from clients to colleagues.
