Once upon a time, we lived in a world where no one expected the companies that sold them soap, shoes or snacks to also help cure diseases, feed the hungry, and protect animal habitats. Sure you'd find the occasional donation can at a cash register, but for the most part, bettering the world was not something you looked to do while shopping or encountering ads.

All of that is rapidly changing. Welcome to the "We First" world - one where people are more socially aware than ever, and companies are pulling their weight in innovative ways to create positive change around the world.

In his new book, We First: How Brands and Consumers Use Social Media to Build a Better World, Simon Mainwaring (@simonmainwaring) discusses the connection among social media, brands, charities, and everyday people. He points to SocialVibe as an example of the power of spreading messages on social media and talks about the incredible movement from a "me" world to a "we" world.

We're so honored to be a part of the "we" movement and thrilled to be included in this inspiring book.

Below, SocialVibe CEO, Jay Samit, sums up "the power of all of us."

"Just a few minutes a day…a click here…a post there…can inspire millions to give back to those in need. On average, SocialVibe users share brand campaigns with 170 of their friends and our members, their friends, and our advertisers continue to use social media for social good each day."

We've had the honor of working with hundreds of your favorite brands that want to make a difference. From uploading images of light to fund solar energy projects through GE, to making virtual beds through Marriott to fund disaster relief efforts, we've been able to help offer actions that highlight the work of both brands and charities – and we couldn't have done it without you.
