Angry Birds is everywhere. It's on every App Store you can think of, on every social network under the sun, and even on a few consoles and web browsers, too.
Then, there's the merchandise - including socks, speakers, notepads, and cookery books - the sequels and spin-offs, the TV show and series of books, and the various bits of Rovio trivia.
To try and catalogue everything related to Rovio's ultra-popular aggravated avians, we've built this A to Z index of the Angry Birds universe. Take notes - there will be a test.
Angry Birds - The original game. The one that started off this whole phenomenon. It launched in 2009, and quickly became a worldwide smash hit. Read our review.
Android - Every Angry Birds game is available to download on Android. The games are free, and supported by adverts and in-app purchases.
April Fools' Day - Rovio fooled its Facebook and Twitter followers in April 2012 by
pretending that a stinky "skunkbird" was going to be a new character in Angry Birds Space. Those cheeky blighters.
Balls - Giant rubber balls, featuring a smug swine's face.
Blue Bird - A scattershot bird that splits into three. In
Angry Birds Space, they're particularly effective in icy situations.
Black Bird - Caustic birds that explode to create shockwaves and destroy close blocks and birds.
Boomerang Bird - A late-stage addition to the bird clan. This twisty toucan can turn around mid-flight, and attack pigs from behind.
Big Brother - A pot-bellied evolution of the classic red starter that can rip through wood and glass like butter.
Blackberry PlayBook -
Angry Birds was even released on BlackBerry's iPad rival: the Playbook. Read our
review of this tablet app.
Boardgame -
Angry Birds went physical with the
Knock on Wood boardgame. Like the
Angry Birds game itself, you fire birds at pigs. Unlike the video game, you have to clear up all the mess when you're done.
Bags - Drawstring bags, plush backbacks, school bags, shoulder bags, and even lunchboxes. Whatever your preference, Rovio will ensure you have the perfect bag to store all your other
Angry Birds junk.
Books - Rovio has published a load of
Angry Birds written material, including sticker books, colouring books, poster books, and a tie-in tome with

Angry Birds veterans. Available as an in-app purchase in

Kovalainen - Finnish F1 driver Heikki Kovalainen was sponsored by Rovio for the Australian Grand Prix last month, and wore an

Keychains -
Angry Birds keychains. Just don't lob them at nearby pigs or you'll be locked out of your house.
Kiss - 'What is flamboyant heavy metal band Kiss doing on a list about
Angry Birds,' we hear you ask. Well, legendary bassist Gene Simmons revealed in 2012 that the band is doing a deal with Rovio for a Kiss-themed
Angry Birds spin-off. A genuinely terrifying prospect.

Angry Birds Space. This time around, you can choose the exact target for the Lazer Bird to home in on.

and download from Apple's Mac App Store. Ca-caw!
