SAN FRANCISCO (AP) -- Apple announced a digital radio service, new MacBook Air laptops and updates to its operating systems for Mac and mobile devices Monday.
The announcements came at the company's annual conference for software developers in San Francisco.
Among the highlights: Apple showed off a simplified look on iPhones and iPads. It is the most radical design change since the iPhone made its debut in 2007. It's part of iOS 7, the new operating system for mobile devices coming this fall.
That system will also come with a new radio service, iTunes Radio. In the past, Apple has sold songs and albums one by one. With iTunes Radio, people will get a continuous feed of music chosen by the service based on what they've listened to and what they've purchased on iTunes. It's free, with ads.
The two-hour keynote kicked off at about 10 a.m. PDT. Apple's Worldwide Developers Conference goes through Friday.
Here's a running account of the event, presented in reverse chronological order. All times are PDT. Presenters include CEO Tim Cook; Craig Federighi, senior vice president for software engineering; and Eddie Cue, senior vice president for Internet software and services.
Cook concludes by touting the new radio service as the "absolute best way to discover new music" and reiterates that iOS 7 is the biggest change ever to the iPhone.
He also unveils a new Apple ad that emphasizes the company's products making life better.
Apple says iOS 7 will be available on the iPhone 4 and later, the iPad 2 and later and the iPad Mini. A test version is available to developers starting Monday. It will be available for everyone else this fall. That's when Apple is likely to introduce a new iPhone as well.
Apple unveils a streaming music service, iTunes Radio. It is built into iOS 7 and works on Apple's mobile devices. It will also work with Apple's iTunes software on Mac and Windows computers.
It's free with ads, though subscribers of Apple's $25-a-year iTunes Match service will get it ad-free. Availability will start in the U.S.
Apple unveils a feature for organizing photos you take on iPhones. Instead of the endless streams of the past, they will be organized into moments -- such as "home" or "trip to San Francisco." Federighi says that while you may not remember when you did something, the device's software does.
Apple also says its Siri virtual assistant will use search results from Microsoft's Bing -- furthering its avoidance of Google services. Last year, Apple unveiled its own Maps app to replace one using Google's mapping service.
The company also says it will come out with a version of iOS built into cars.
Apple takes a jab at one of its rivals, Samsung Electronics Co. The South Korean giant has been touting Android phones that let you share photos and other content by bumping phones together. Samsung phones have a near-field communication chip that iPhones lack.
Federighi says iOS 7 will let you share content wirelessly with a feature called AirDrop.
He says, "No need to wander around the room bumping your phone with others."
Apple shows off new features in iOS 7.
Apple demonstrates a new weather app with animation: It shows thunder when a thunderstorm is forecast, for instance. The calendar has been cleaned up and looks more streamlined. You can also get to your contacts list quickly while reading messages by swiping from the left of the screen.
Also coming to iOS 7: full multitasking. In the past, the ability to use multiple apps at once was limited.
You can also swipe up from the bottom to access a control center, for such functions as turning on the airplane mode and adjusting brightness. It's similar to a feature available at the top on rival devices running Android.
Apple's software will also figure out which apps you tend to use and make sure content is regularly updated for those.
Cook touts the advantages of Apple's iOS software for mobile devices and introduces a new version, iOS 7. He says it's the biggest change to the system since the iPhone's introduction in 2007.
Apple's design chief, Jonathan Ive, appears in a video showing a unified look that is applied across the system.
Icons in iOS have had a three-dimensional look that tries to mimic the real-world counterparts of certain apps. For instance, the icon for the Notes app looks like a yellow notepad and the Contacts app is represented by a leather-bound address book.
