What is social media?

Social media is all about online platforms where people create, share, and interact with content—think posts, photos, and videos. Platforms like Facebook, Instagram, and X let users connect with friends, follow brands, or join communities. It’s a space that’s reshaped how we communicate, market products, and stay entertained in the digital age.

A quick history

Social media started taking shape in the 1980s with basic online forums. But it really hit its stride in the early 2000s with platforms like Friendster (2002), MySpace (2003), and Facebook (2004). These sites introduced the idea of personal profiles and online networking. Today, social media includes everything from X’s quick updates to YouTube’s video hubs—each platform bringing something unique to the table.

Types of platforms

Not all social media is the same. Here’s a breakdown of the main types:

  • Social Networks: Think Facebook, LinkedIn, and X—great for connecting and chatting.
  • Media Sharing: Instagram, YouTube, and Pinterest shine with photos and videos.
  • Discussion Spaces: Reddit and Quora are where people dive into topics and questions.
  • Blogging Platforms: Medium and WordPress let users publish their thoughts.
  • Messaging Apps: WhatsApp and Messenger keep conversations flowing in real time.

How people use it

Social media has a ton of uses. Individuals catch up with friends or discover news, while businesses promote products and chat with customers. It’s also a go-to for entertainment—scrolling TikTok or watching YouTube feels like second nature to many. Basically, it’s a tool that fits whatever you need it for.

Why it matters

Social media has changed the game. It brings people closer, gives brands a voice, and spreads ideas fast. But it’s not all smooth sailing—privacy worries and misinformation keep us on our toes. Still, with billions of users, its influence on how we live and work is undeniable.

Key metrics to know

If you’re tracking social media, these terms come up a lot:

  • Followers: How many people subscribe to your updates.
  • Likes: A thumbs-up for your content.
  • Shares/Retweets: When someone passes your post along.
  • Comments: Feedback or chatter from users.
  • Reach: The number of unique viewers.
  • Impressions: How many times your post pops up.
