E-Holiday cards are a fun and green way to send greetings, and JibJab is one of the most successful e-card companies out there. It's the personal video aspect that makes such a popular hit.
USA Today has an in-depth article about the founding and growth of JibJab. Started by two friends in 1999, JibJab got it's big break in 2004 with the viral parody of "This Land is Your Land" featuring George W. Bush and John Kerry. The popular video that led to calls from venture capitalists, and from there the company has grown wildly.
By enabling users to insert pictures of themselves, family and friends, JibJab created a great product that's personalizes the parody. For this holiday season they're offering cards that feature scenes from "It's a Wonderful Life," "A Christmas Carol" and more. You can also "Elf Yourself" through a promotion from Office Depot.
