One thing I loved about the tech world while I was growing up was that it was consistently doing more with less. Wikipedia displaced Encyclopaedia Brittanica by being both better and free. Hotmail was a clear win over AOL and Yahoo's offerings and then Gmail was faster and handled spam better while giving more at every price point (including free). Computers became both faster and cheaper. Amazon and Netflix broke down even the movie industry and ended the $70 per tape movie sale price.
The offerings on the linked page are mostly things that would be out of the budget of an American family living on a median income. I won't call out any specific examples or hurt feelings, but a random sampling of several companies of any part of the list (other than non-profits) will show a clear trend.
It's hard to say if the same was true 20 years ago and those few companies that broke out into famous successes happened to be particularly aimed towards a broad appeal, but it's clear the current trend is doing more with more.
