18. Netflix

Sure, other companies allow you to rent movies through the mail or watch them instantly for a flat fee with no due dates now, but Netflix achieved verb status by leading that rental revolution (have you ever said, "I have to Blockbuster that!"? Didn't think so.). We may never have another holier-than-thou Quentin Tarantino film geek who came up as a video store clerk looking down on us for renting From Justin to Kelly, but we think we can live with that.

Netflix has more than 55 million discs and has mailed over two billion DVDs to customers since the company started in 1997. People need to get out more often.
