Each day, millions of people access a social media platform to connect with friends and family, consume news and upload photos. Each day, these networks evolve as more people find new and interesting ways to use the platforms in their everyday lives.

Social Media Day is a celebration of these networks and their users, and Mashable is excited to announce that the fifth annual Social Media Day is returning on June 30, 2014.

Mashable launched Social Media Day in 2010 as a way to recognize and honor the digital revolution happening around the world. Social media is clearly celebrated and scrutinized on a daily basis, but Social Media Day is a moment for everyone to take a step back and reflect on the its broader impacts.

Last year, thousands of people participated in the hundreds of Social Media Day events around the world. Some of the most highly-attended events were hosted in Australia, Costa Rica and Sri Lanka, while U.S. cities including Detroit, Miami and San Diego attracted large crowds. Mashable hosted its own Social Media Day event in New York City, where thousands of attendees enjoyed networking, refreshments and music.

You're invited to celebrate social media with us by attending or hosting a Social Media Day Meetup in your area. For updates and to see what other organizers around the world are planning, follow @MashableEvents on Twitter or join our Mashable Meetup Organizers group on Facebook.
