In the booming age of technology, it’s nice to see that one holiday tradition remains just as strong as ever, sending Christmas cards to friends and family. What’s even more unbelievable is that we still predominately send those cards in the regular, plain old mail.

The first known Christmas card was sent in the middle of the 19th century in England. It’s hard to believe in this day and age that they remain so popular. Pam Danziger, president of Unity Marketing, is the lead researcher in all things greeting cards. She claims that two-thirds of the people surveyed sent holiday greeting cards in 2012. Those results are about the same as they were four years ago.

In fact, yesterday, December 16th was the busiest day of the year for the USPS. The company estimates that about 600 million cards and packages raced through post offices across America.

And, you know who else sends Christmas cards? Celebrities. Here’s one from Mr. Playboy himself, Hugh Hefner, his lovely wife Crystal Harris and their dog Charlie. You may have not received the card in the mail, but you can check out it on Hef’s Twitter feed. Note the matching pjs.
