Rosetta Stone Inc. has appointed a permanent CEO. John Hass, a board member who took the reins from former CEO Stephen Swad nearly a year ago, is the new chairman, president and CEO of the company. He replaces Patrick Gross as chairman.

Rosetta Stone is remaking its model and mission after years of faltering revenue, mounting costs and lack of focus. The company is moving away from its longtime customer base - casual language learners looking to learn Spanish or Italian before a trip abroad - toward corporate and educational clients looking to promote English literacy.
