Apple has marked the 10th anniversary since the first iPhone went on sale.
More than one billion iPhones have been sold since the model was launched on June 29, 2017.
Apple, led by Tim Cook, is now one of the wealthiest companies in the world, with iPhone revenue topping more than £25.4 billion, according to the firm's most recent quarterly financial results.
Ten years on since first hitting the markets, one analyst has described the iPhone as having "dramatically changed the way people live".
Since 2007, Apple has released 11 generations of the device.
The company is reportedly planning to unveil a special 10th anniversary edition of the smartphone in September.
The iPhone was the first modern smartphone to successfully abandon a physical keyboard for a multi-touch screen.
According to one industry expert, the iPhone's mobile internet connectivity and camera were the driving forces behind the device's success.
Cathy Boyle, from industry analyst eMarketer, claimed the phone also paved the way for Snapchat and Instagram, among others.
"For millions of people worldwide, the iPhone is about the internet and the camera," Ms Boyle said.
"Having access to the internet within arm's reach at all times has changed the way people consume media, buy products and communicate.
"The camera alone has made communication far more visual, as people share millions of pictures and videos via SMS, social networks and messaging apps.
"The camera has also empowered every iPhone owner to become a content creator."
In recent years, Apple has faced increased competition from rivals Samsung and Google on the smartphone market.
In the UK market, the iPhone is the second most popular mobile platform behind Android.
