I just realized today that the websites we check daily using SimilarWeb, the Wayback Machine for website history, and Amazon's smart speaker Alexa are all interestingly interconnected, and the tech world is also a small community.

In 1996, Brewster Kahle founded Alexa Internet, focusing on clickstream data analysis, studying which new websites users would click on after visiting a particular site, which later became a website traffic analysis tool.
In 1999, Amazon acquired this site with $250 million worth of Amazon shares, hoping to help analyze user behavior across different websites to guide more people to place orders on Amazon.
After Kahle's company was acquired, they turned the web crawler capabilities and resource library built at Alexa Internet into an NGO - Internet Archive, and to this day, they maintain it with their own funds for public benefit.
Anyone can see what any website looked like on any given day over the past few decades here.
Amazon shut down this business in 2022, but they really liked the symbolism behind Alexa — the world's largest library once, the Library of Alexandria — so they named their smart speaker product after it.
As a result, visiting now redirects to the Alexa speaker.
SimilarWeb, as a user impacted by the shutdown, has also become one of the leading companies in this industry.
