As anticipation builds ahead of WWDC 2018, rumoured to take place from 4-8 June in San Jose, we've found it instructive to remind ourselves of the major product announcements we've enjoyed at WWDC gatherings over the past decade and more.

Apple's Worldwide Developer Conference has been an important event on the Apple calendar since as far back as the 80s, but has become increasingly known for Apple hardware and software announcements since around 2005.

Here, we take a look back at Apple's most significant WWDC announcements. If you'd like to see for yourself what the fuss is all about, here's how to get WWDC tickets.

WWDC 2017

WWDC 2017

When: 5-9 June 2017

Where: McEnery Convention Center, San Jose

What was announced?  macOS High Sierra, iOS 11, watchOS 4, tvOS 11, new iPad Pro models, iMac Pro, MacBook upgrades; HomePod.

The 2017 event was a blockbuster! As well as the now-customary raft of updates to Apple's four software platforms, there were new iPads (including an entirely new size), minor MacBook updates, iMac news (including the iMac Pro) and the hugely anticipated HomePod.

What an event. You can catch up on all the news and excitement in our dedicated WWDC 2017 report.

When: 13-17 June 2016

Where: Bill Graham Civic Auditorium & Moscone Center West, San Francisco

What was announced? macOS Sierra, iOS 10, watchOS 3 and tvOS 10.

There were four main areas in Apple's WWDC 2016 press conference - tvOS, macOS (formerly known as OS X), watchOS and, of course, iOS. There were updates across the board, but the most impressive came in the form of iOS 10.

iOS got a completely redesigned lock screen and notification system and enhanced 3D Touch shortcuts. And the Music app was given a much simpler design that is easier to navigate and use.

Where: Moscone Center, San Francisco

What was announced? iOS 9 and Mac OS X 10.11 'El Capitan' were the big-name software updates. watchOS for the Apple Watch got its first big update, too. But the biggest announcement of the night was Apple Music, the company's answer to Spotify.

WWDC 2014

WWDC 2014

When: 2 June

Where: Moscone Center, San Francisco

What was announced?

iOS 8 and OS X 10.10, both of which represented significant changes and improvements over the previous versions. There were no hardware announcements.

To prevent 2013's two-minute sell-out fiasco from happening a second time, Apple decided to allow developers to register for the conference over a period of five days, after which the company randomly selected 5,000 attendees from the applicants.

When: 7 June

Where: Moscone Center, San Francisco

What was announced?

In 2010, Apple announced the iPhone 4 and officially renamed its iPhone OS as iOS. The FaceTime and iMovie app for iPhone were unveiled too.

WWDC 2010 sold out in just eight days. Not much attention was paid to Mac OS X this year, though, which frustrated some developers.

When: 8 June

Where: Moscone Center, San Francisco

What was announced?

Sold out for the second year in a row (a trend that has continued right through to 2013's WWDC), WWDC 2009 was host to the unveiling of iPhone OS 3.

Further demonstrations of Snow Leopard took place at the event, the 13in MacBook Pro was unveiled, and the 15in and 17in MacBook Pros were refreshed. If that's not enough, Apple also announced the iPhone 3GS during the event.

Apple's marketing boss Phil Schiller took to the stage to present the WWDC keynote in 2009, in the place of Steve Jobs due to illness that caused the co-founder to take medical leave from the company.
