The dot com bubble was an economic event during the end of the 20th century after many speculative investments had been made into new internet companies. Many companies died there, but the few that survived would come back to thrive later. This bubble also actually helped the publicity of the internet, which would help advancements in the technology to be made.
There were several different things that had to do with the dot com bubble. Firstly, there were a LOT of speculative investments, which led to inaccurate evaluations of a company’s worth. These investments were all based upon the brand new idea of the internet, which had not had any proven value yet.
There were several companies that survived the dot com bubble, and the ones that did would become some of the biggest sites, like Amazon, eBay, and Google; however, the vast majority of companies went under, never to see the light of day again.
In 2000 and 2001, the bubble burst. People started to realize that their investments had not been worth it, and so lots of companies decided to cut their losses, meaning shutting down their businesses and letting all their employees loose, which caused a lot of people to lose their jobs.
The Dot Com bubble actually impacted the development of the internet for the better; with so many companies starting to develop, it pushed for improvement in the space, and the companies that survived the bubble would go on to become some of the biggest in the market.
