While most of us were still picking up our weekly print edition, the Onion was launching an audacious — and always satirical — multimedia empire. Celebrating its long history, it offers an archive that stretches back more than 20 years; the Onion is also very much in the present, featuring semi-daily videos that spoof everything from C-Span to the Today Show to ESPN. It also serves up daily audio podcasts (known as the Onion Radio News) and some of the funniest slide shows on the Web. Meanwhile, as any serious lover of the arts will tell you, the publication's online A.V. Club features exceptionally good arts reporting (as well as a trove of erudite user comments).
