According to the gospel of innovation on the Internet, there was search before Google, social networking before Facebook and music playing devices before the iPod and yet these services and devices completely changed the way we think about the Internet and content.
If you believe in this version of how the current big players came about, the logical next step is to conclude that the next big thing is probably already out there in one form or another. It could be that the actual company that is going to strike gold has already been founded or just that the market where it will enter has begun to develop.
Many different services and technologies have been floated as possible next big things. NFC, Twitter/microblogging, big data and many more have been mentioned but none of them are even near being widely accepted as the next big thing.
Where would you place your bets? Where do you see the next big thing emerging?
