But the risk of losing an employee or two doesn't seem to have deterred employers from embracing new approaches to training. Lynda.com reports that 5% of its members now watch its training videos on smartphones. While that figure might seem small, it has more than doubled over the past year and continues to rise.
It remains to be seen whether it will one day be commonplace for IT professionals to watch training videos starring Hollywood celebrities on smartphones. What is certain is that offering high-quality, creative training via a variety of delivery mechanisms is now a business imperative.

Behind the Lens of an IT Training Video
Not many people would disagree with Tom Graunke that IT training is long overdue for an overhaul. "Can you name the last time you did something in e-learning and said it was amazing?" asks Graunke, CEO of Stormwind, an IT training firm in Scottsdale, Ariz. "It's boring, and it's flat."
But the process of looking for ways to breathe new life into IT training tools can itself offer lessons in technology. Take, for example, Stormwind's experience developing its HD Live training system. Used by leading tech vendors such as VMware and Cisco, these live, interactive high-definition IT training videos feature an instructor standing in a control room surrounded by computer monitors. Throughout an hourlong online session, the instructor is seen in front of various screen captures and animated slides while lecturing and fielding questions from audience members in real time.
To make this online learning technology a reality, Stormwind had to find a way to deliver live, high-definition video to a standard Web browser. That's a considerable challenge given that the majority of today's browsers are barely sophisticated enough to handle Flash.
First, Stormwind built a studio with green-screen technology and created software-generated 3D renderings of various backgrounds, to make it look as if instructors are literally walking viewers through screen captures and slides when, in reality, they're just talking to a green wall.
But because typical Internet connections can't support the transmission of green-screen technology, Stormwind had to find a way to compress the massive, high-resolution files. It uses a mix of XML code and Java scripts to deliver the files to Flash media servers, which are designed to stream video to a browser regardless of an end user's device and bandwidth limitations. Essentially, the servers trick the browser into thinking that it's dealing with a single image rather than a hodgepodge of Flash, HTML, green-screen technology and 3D renderings. A Stormwind producer can replace green-screen images on the fly while Flash media servers prompt the browser to refresh 30 times a second for a constant feed of live images.
