A photo can be as a powerful – if not more – than words, and with the click of a button on a phone, millions of people around the world will instantly view a photo that can make them laugh, think, and possibly encourage change. So it’s no wonder that Instagram is such a powerful tool, and one that people warm to given our near-obsession with pictures.

Whether it’s something silly – usually involving animals, something funny – usually involving selfies, or something important – usually something controversial, Instagram has shown that it’s the most powerful social sharing site. Here are ten of its most important moments to date.

The Oscars selfie

At the 2014 Oscars, host Ellen Degeneres decided to take advantage of the worldwide phenomenon that is ‘the selfie’ by gathering some of the most biggest names in Hollywood for a photo. It was a brilliant idea, with Bradley Cooper, Jennifer Lawrence, Meryl Streep, Julia Roberts, Brad Pitt and Kevin Spacey all getting involved, and it received 1.3 million likes on Instagram.

 Richard Branson’s Inspirational Message

While many of the world’s most influential people will post selfies (which isn’t necessarily a bad thing!), others choose to inspire in a somewhat different way. Richard Branson – one of the most successful men on the planet – uses his power to inspire, with posts such as this one: “To stand still today is to go backwards – and quickly.”

Cara Delevingne’s weird selfie

Cara Delevingne probably underestimated the power of a weird selfie. While most young models and actresses post photos of themselves looking as perfect as possible, Cara decided to show that making a weird face is just as fun, thus proving that celebrities can be normal too.

The breastfeeding photo that got a woman banned

Heather Bays got banned from Instagram after posting a photo of her breastfeeding her daughter. It wasn’t at all tasteless, and unsurprisingly people were pretty furious about the whole thing. Thankfully, she won the battle and she was eventually reinstated.
