WaterPlus

Functionally and chemically identical to regular water, WaterPlus was a company started by comedian Ricky Merchant in the year 2031, to poke fun at consumer habits - and to settle a bet that he could advertise a new brand of water as being "what the plants crave", and that people would buy it. Completely unexpectedly, people began to buy WaterPlus in waves, and despite abandoning the company shortly after it's initial success, and being an outspoken opponent to the company (now run by another person) - WaterPlus continued it's upward trend of success.

By 2040, WaterPlus was a billion-dollar company, despite selling a product completely identical to every other brand of bottled water.
