I have written the praise of TASCHEN books before and I received the latest book from them today and they continue to impress. Advertising Now! Online is the most complete and best collection of best-in-class online advertising I have seen. All 448 pages are well laid out with large photos and the work is organized by subject. Each chapter also has an article from one of the agencies in the book about their biggest campaigns and what went in to creating them.
The best thing is that the book also contains a DVD which shows all of the work in motion which brings it to life and shows it the way it should be seen. Before this I have always enjoyed the books from ONE show every year but this is a much more international and complete collection and something should is a great desk reference for online advertising designers.
