1) A letter that hoards of businesses and websites put in front of their names and products to make them sound cool. The trend was started by Apple Inc. and since then countless companies have jumped on the bandwagon and done the same thing.

2) A letter which, when placed in front of any word, indicates the online version of that thing; regardless of whether the online version actually exists or not.

1) I just went to iGoogle on my iMac and searched for BBC iPlayer but then someone texted my iPhone to tell to me that iMesh have been taken down off the web.

2) I was getting iBullied by this iThug and I kept hoping the iPolice would show up and kick him into iJail.

cout << "All work and no play
makes Jack a dull boy.\n";
}
return 0;
}

A letter added to the beginning of words by companies who think it will sell more of their products.

Everyone else: "Brilliant!, simply brilliant! It will sell just like an iPod!"
