Adele dominated music this year, and iTunes was no exception.
The British songstress had iTunes' best-selling album and song, and was named as its top artist.
Adele's "21" is the year's top-selling album with 4.8 million copies sold. Some of those numbers came from iTunes, where the album was the most popular; following behind was "Sigh No More" by Mumford & Sons, Lil Wayne's "Tha Carter IV," Jay-Z and Kanye West's "Watch the Throne" and Coldplay's "Mylo Xyloto."
Adele's No. 1 hit "Rolling in the Deep" was the best-selling song. At No. 2 was LMFAO's "Party Rock Anthem" (with Lauren Bennett and GoonRock), followed by Katy Perry's" Firework," Bruno Mars' "Grenade" and Cee Lo Green's "Forget You."
ITunes picked Nicki Minaj as its breakthrough artist of the year, Foster the People's "Pumped Up Kicks" as its song of the year and "Wasting Light" by the Foo Fighters as album of the year. Foo Fighters frontman Dave Grohl said in a statement he was excited to be noted for "an album made in my garage, totally analog to tape, without the help of any computers at all."
"Angry Birds" was the top paid iPhone and iPad app, "The Social Network" was iTunes' best-selling movie and "Doctor Who" was the best-selling season TV series. (An episode of "Walking Dead" was the best-selling TV episode.)
The best-selling fiction book was "The Help," while "Steve Jobs," the book on Apple's late founder, was the best-selling nonfiction book.
