Ideas/Products/Services That Should Have Gained Prominence, But Didn't In The End?

I got thinking about this one when thinking about ideas/services or products that bizarely actually did catch on - bicycles and cycling, taxis, which are a little odd but nonetheless are universal! Also I was surprised when studying marketing that such a certain winner as colour tv had to be launched 3 times in the USA before it gained some acceptance. So, though none come readily to my mind what ideas/services or products never quite made the grade, but should have?
 
What no replies yet! Actually one that fell out of favour for a very long time was womens' soccer in the UK. By the 1920s some womens' matches were getting crowds at a level that made the football authorities nervous for the future of the mens' game so they clamped down on it! Actually one of the reasons for such huge crowds was probably that men got to get a glimpse of womens' legs along with no doubt some skillful players!
