Bloomberg, a premium-priced leader in its core financial data market, is using disruptive discounts as it tries to turn Bloomberg Law from a niche pilot product to an alternative to LexisNexis and Westlaw, the leading legal information brands.   The unit forms part of the data provider’s drive to diversify beyond the banks and investment groups that make up the core customers for its eponymous terminals. In the past year the group has also bought Business Week magazine and entered the Washington regulatory and legislative information market with Bloomberg Government.  Source:  Yahoo Finance
