Bangalore: Today is so complicated, and we humans have become so accustomed to using alternative, easier ways to do things, that sometimes, the most obvious ideas elude us.

So what do you do when you see a perfectly good idea that you could have thought of, and didn’t? What if that idea sold to make millions, even billions in cash?

Here are some of those simple, uncluttered ideas that went on to make it big in the world of technology. Burn with envy as you read about:

1. Million Dollar Homepage

Originator(s): Alex Tew

Year: 2005

Worth: $1,037,100

How it took off: Alex Tew needed to raise money to go on and do a business degree, (since a study loan would take years to pay off); and his idea made more than a million in 5 months.

Tew saw an opportunity to make millions-- in selling out space.  He made a homepage, one that consisted of 10X10 blocks of pixels, and sold them out at $10/block. Advertisers could put on any picture, from their logo to any other picture, which would be linked to their site at the back end. The last 1,000 pixels were put up for sale on eBay. His was so deceptively simple and neat an idea that he cashed in on $1,037,100 in just about 5 months!
