An authoritative, addictive and highly entertaining book, an A-Z of the buzzwords that define the 21st century. It contains over 75 entries that explain where concepts like 'the tipping point', 'the long tail', 'urban tribes' and 'metrosexual' came from, what they mean, and what their critics say about them. It crosses several genres, including business, reference and popular psychology, and will appeal to readers of "Freakonomics", "Wikinomics" and "The Wisdom Of Crowds".
