2000 sees the rise and burst of the dotcom bubble. While myriad internet-based businesses become present in everyday life, the Dow Jones industrial average also sees its biggest one-day drop in history up to that point. By 2001, most publicly traded dotcom companies are gone. It’s not all bad news, though; the 2000s see Google’s meteoric rise to domination of the search engine market. This decade also sees the rise and proliferation of Wi-Fi — wireless internet communication — as well as mobile internet devices like smartphones and, in 2005, the first-ever internet cat video.
