The iPhone turned 10 years old on Thursday, and many people took a moment to remember the first time they saw the Apple device. When it came out on June 29, 2007, people were lining up outside stores around the world to buy the phone. It was a big success for the computer company that made the Macintosh and the iPod. The hashtag #iPhoneAt10 was trending on Twitter most of the day. One person called it a “revolution,” and others posted about the phone’s “evolution” in the last 10 years. “Massive” is the word CNN used to describe the businesses that grew up around the phone’s popularity. The current version is iPhone 7, but many people expect an iPhone 8 to come out soon. Some technology reporters say the next iPhone will come out in September, and it will be even larger than the ones we see today.
