The legal profession is based on certain essential notions of ethics and customary professional principles which a lawyer is supposed to follow. However, lawyers do not live in a social vacuum. Widening horizons of commercialism, encroaching upon every single course of human interactions, lawyers find themselves at the crossroads. A visible divide is seen between two schools of thoughts, one that sticks to the original notions of ``professionalism`` and the other who discard it for a more modern ``commercialized`` approach towards the profession. With ever increasing ambit of legal services, questions have been raised as to the shifting paradigm of legal profession from professionalism to commercialism. Professional Ethics and advertising by Lawyers, is a small endeavor to analyse this dichotomy focusing on the propriety of lawyers advertising in a world where everything under the sun is capable of being marketed. The book discusses in comprehensive details the professionalism debate with respect to attorney advertising, arguments for and against the practice and delineates the evolution of the attorney advertising in United States and India.
