Some technologies invented and improved during the 1990s:

The World Wide Web and HTML are created by Tim Berners-Lee^[4]^[5] and eventually displace the Gopher protocol.
Microsoft introduces Windows 95 and later Windows 98 to the market, which gain immediate popularity.
The development of Web browsers such as Netscape Navigator and Internet Explorer makes surfing the World Wide Web easier and more user friendly.
The Java programming language is developed by Sun Microsystems.
Businesses start to build E-commerce websites; E-commerce-only companies such as Amazon.com, eBay, AOL, and Yahoo! grow rapidly.
E-mail becomes popular; as a result Microsoft acquires the popular Hotmail.com webmail service.
Instant Messaging and the buddy list becomes popular. AIM and ICQ are two early protocols.
The Year 2000 problem (commonly known as Y2K), the computer glitch disaster expected to happen on January 1, 2000.
Microsoft Windows operating systems become virtually ubiquitous on IBM PCs.
Development of the free Linux kernel is started by Linus Torvalds in Finland.

Digital Cameras become commercially available and become more affordable over time.
The popularity of CDs keep expanding.
The first MP3 player, the MPMan in 1998, is released.
DVDs become available in the US in 1997 and rapidly increase, making video cassettes obsolete.
Plasma flat panel televisions become commercially available later in the decade, competing against CRT televisions.
Full Color Flat Panel Computer monitors are released commercially to the public in the mid-to-late 1990s
The first HDTV broadcast airs in 1990
Memory cards become available
USB ports become popular in computers, although the USB flash drive wasn't available until 2000.

Web TV and digital TV becomes popular later in the decade.
Active matrix laptop computers become popular and easier to afford.
PDAs (Personal Digital Assistants) become popular in the mid-1990s with the release of the touchscreen Apple Newton in 1993, although it has a monochrome screen. Later in the late 1990s, the first full-color PDAs are released, but they consume a lot of battery life.
Digital Video Recorders, abbreviated as DVRs, are released in 1999.
Satellite TV becomes commonplace.

As mentioned, the World Wide Web grows rapidly since the start of it in 1991.
2G (2nd generation) mobile phones are launched, which uses digital waves rather than previous analog radio waves.
