At the beginning of almost every industry, the available products and services are so expensive to own and complicated to use that only people with a lot of money and a lot of skill have access to them. A disruptive technology is an innovation that simplifies the product and makes it so affordable that a whole new population of people can now have one and use it at the beginning for simple applications, and then it improves to the point that it makes the old technology obsolete.

Clayton ChristensenEvery time you take someone figuratively by the hand and introduce him or her to Jesus Christ, you will feel how deeply our Savior loves you and loves the person whose hand is in yours.
