Example of Oligopolistic Markets...?

Yeah, go look at the definition of oligopoly - markets dominated by a few enterprises, often high barriers to entry etc etc. Juuustbruger you need to do some homework before you can talk about high level economics!

I haven't done any homework since I was about 11, but thanks for the advice anyway.

If you read my post, you'd see I wasn't disputing the meaning of the term 'oligopoly' - I was simply stating that it's better to be specific and if you're dealing with two it's a 'duopoly' (and yes, I used the wrong term initially).
