Oprah, the self-made success story she is, has left her mark on various different areas of the media industry. She's virtually a household name in the U.S.
Opera, on the other hand, is an alternative browser that runs on a multitude of desktop and mobile platforms. Opera isn't quite a household name in the same way that Firefox is, but it can hang with all the big boys.
Believe it or not, some people get confused between Oprah and Opera. As a send off to the Queen of TV, Opera has posted some of its funnier emails from people who emailed the Norwegian company looking for Oprah.
