(2) (Opera) A Web browser for Windows, Mac and Linux from Opera Software, Oslo, Norway (www.opera.com). Developed at Telenor (Norwegian Telecom) in 1994 and commercialized by Opera in 1995, it is noted for its fast rendering of Web pages. Opera was the first browser to offer a host of unique features such as enlarging text and graphic elements on the page and displaying multiple windows with only one instance of the program running. Having had both paid and ad-supported versions, the paid version was made free in 2005.
For Cellphones and PDAs
Opera Mobile and Opera Mini are versions for cellphones and PDAs. The Opera Platform is for developers who want to offer advanced Web applications on mobile phones.
In 2010, Opera was the first third-party mobile browser authorized for the iPhone. If a Web site is not mobile enabled, Opera first "greeks" the text on the home page (top). One tap on the screen enlarges the page to focus on pertinent text (bottom). See
