The New York Post is reporting
that the electronic form of the Wall Street Journal has "profit margins at least 20-fold higher than print". The publication is losing some customers, but many are moving to the less expensive online version, which is a big part of its future.
While I doubt that total profit figures of the online version are anywhere close to the overall print numbers, it is unlikely that the profit margins will be ignored.
After so many years, we finally see multiplying signs that the ebook industry is about to explode. It's about time!
