Reminds me of my 1996 article on the Top 25 Search Engines. I wrote a short paragraph about each and rather than ranking all I ranked my fave five, identifying strengths and shortcomings. The big “Wow” is that Google was not even on the list. They came into a crowded playing field with something consumer friendly and easy and superior results… and the rest is history. They became the Kleenex of search engines.
Your knowledge of the players in this field would be invaluable to anyone sitting at a marketing desk.
