Rockwell International
In 2001, Rockwell International split into two companies. The industrial automation division became Rockwell Automation, while the avionics division became Rockwell Collins. The split was structured so that Rockwell Automation was the legal successor of Rockwell International, while Rockwell Collins was the spin-off. Rockwell Automation retains Rockwell International's stock price history, and continues to trade on the New York Stock Exchange under the symbol "ROK".
