The Keurig was launched in 1998. It was one of the first machines developed to make a single cup of coffee at one time.
Nearly two decades later, Keurig racks up about $4 billion in annual sales, and the brand has become synonymous with in-home coffee makers.
Keurig's 'K-Cup' system -- basically individually filled coffee pods -- eliminated the need to grind your own beans and did away with pouring half-empty coffee pots down the drain.
Others are now replicating this convenient, single-serve model, not just with coffee but with other inventive uses.
Here are a few examples of companies that are putting their own unique spin on the Keurig model. Most of these are still in development but are available for pre-order on their websites.
