Odd Word Out

I had fun devising a little vocabulary quiz today. Some words are acronyms that have entered the English language recently, others are newish compound words, some are blend words and some abbreviations. A lot of them have a connection with technology. I have used Word Spy - Top Hundred as my source of information and also wikipedia.


From the list of words below find one which is different and ask yourself why is it different from the other three? Please note- I had to invent something which didn't fit so hopefully you will be able to work out which one differs. Please do post a comment if you feel some of the words are a bit ambiguous and I will modify as necessary!
