I was getting tired of it, I mean, Come on! 5 years of the same thing! Unacceptable!
The original WeatherStar lasted, what, five years? Then the WeatherStar III came out with expanded products, and that lasted about another couple of years to a few years, depending on when you got the 4000. Then the 4000 lasted most of the '90s until the XL came out, followed by the IntelliStar. Systems weren't so easy to update, so what was released had to last for a while with very few cosmetic changes.
As another example, during the "Weather You Can Always Turn To" era, fonts, graphics, maps, title banners, etc., stayed pretty much the same for years with hardly any changes at all.
It's really only lately that people demand constant changes, everything new, and everything now. Unfortunately for the broadcasters, it's their job to keep up with public demand, so they have to spend money making changes, releasing updates as soon as possible, and so on. We saw the little glitches that plagued The Weather Channel throughout the day today. Microsoft Windows is guaranteed to never be in 100% working condition when a new version is released because they're so anxious to get something new on the market as soon as possible.
Sometimes change for the sake of change isn't necessarily the best thing.
