Infogrames chairman and CEO Bruno Bonnell has taken up the reins at GT Interactive as chairman and CEO. Bonnell is filling the positions left vacant by the departure of GT CEO Thomas Heymann and COO John Baker from GT's executive management team. Los Angeles residents Heymann and Baker both decided to leave in part because of the company's decision to remain headquarted in New York. The moves follow Infogrames acquisition of a 70 percent stake in GT, and could signal the start of Bonnell's efforts to merge the two companies. Bonnell has proposed that GT Interactive and Infogrames merge their North American operations, and GT has appointed a special committee of outside directors to consider the proposal.
