#GivingTuesday = Mobile Tuesday

It's official -- we're proud to announce that the second annual #GivingTuesday was a success! A look at initial PayPal data shows year over year growth and -- we believe -- offers proof that the transformation of giving is clearly underway.

On Dec. 3, 2013, #GivingTuesday, PayPal saw a 123.8 percent increase in U.S. charitable mobile and online donations compared to #GivingTuesday 2012. The top five cities donating the most money through PayPal from mobile devices were: New York, San Francisco, Chicago, Los Angeles and Houston. The top five cities that made the most mobile donations (by count) were: New York, San Francisco, Los Angeles, Chicago and Brooklyn. And the largest mobile donation we saw was $5,000! Imagine that -- we are not just talking about fives and tens here -- handing over $5K with a touch of your mobile device proves it truly is a new world for fundraisers.

Seeing the way consumers, companies and charities rallied online and via social networks on just one day, #GivingTuesday, was truly inspiring. It showcased the potential, the opportunity and the impact that can be made when consumers are mobilized to make online and mobile donations. As we have seen, digital giving offers donors an easier way to give, where, when and how they want, while simultaneously providing charitable organizations with a more efficient way to accept donations.

Neal Litvack, Chief Development Officer at the American Red Cross, recently stressed the importance of mobile and online giving to their business, "PayPal is helping donors make contributions to the Red Cross easier and more convenient across devices and screen sizes. PayPal's solutions have been easy for us to install, make changes and provide the kind of availability needed during high peak traffic periods."

While we at PayPal are thrilled with the success of #GivingTuesday in driving online and mobile donations, we know this is just one step in the right direction. Though technology continues to transform our lives, we know that more traditional methods of giving, such as check-writing, still make up the vast majority of fundraising for today's nonprofits. In fact, various reports show that digital giving accounts for only two to 10 percent of charitable contributions today.

As #GivingTuesday turns into just any Tuesday in December, let's continue to embrace technology and all of its potential to power giving the rest of the year and beyond. To continue to do our part, we want to remind donors that holiday giving cannot end with #GivingTuesday -- is our lighthearted way of encouraging PayPal users to give digitally through Dec. 31. In the spirit of holiday giving, 100% of donations made through this site will go directly to the nonprofits and PayPal will add the cost of 12 stamps -- $5.52 -- when donations of $25.00 or more are made. Please, join us in Stamping Out Checks ... for GOOD!

For more ways to get involved and find an opportunity right for you, please This post is part of a series produced by The Huffington Post in celebration of #GivingTuesday, which will take place this year (2013) on December 3. The idea behind #GivingTuesday is to kickoff the holiday-giving season, in the same way that Black Friday and Cyber Monday kickoff the holiday-shopping season. We'll feature at least one post from a #GivingTuesday partner every weekday in November. To see all the posts in the series, click here; follow the conversation via #GivingTuesday and learn more here.
