After reading the article I must agree with the authors opinion and his experience that formed this opinion. Having watched the Hawaii Ironman live once, however not all the way through, I never watched it again in that format. I do watch the taped versions as they are far more interesting and, being condensed make viewing much more focused and enjoyable.
The same needs to be done with cycling's long stage races and even one day classics. Content is the key to interest the average Joe and keep the enthusiast tuning in to watch.
