Cablevision says Brian Sweeney will replace James Dolan as president of the company, and it named Kristin Dolan chief operating officer. That position had been vacant. Sweeney and Kristin Dolan have both worked at the Bethpage, N.Y., company for more than 20 years, and they are both directors of the company.

Kristin Dolan, 48, is the wife of James Dolan, who will remain CEO. Sweeney, 49, is married to Deborah Dolan-Sweeney, James Dolan's sister and also a director of the company. Cablevision was founded by Charles Dolan, who is still chairman of the company, and six of his children are on the board of directors, as is his brother-in-law Edward Atwood.

James Dolan, 58, has been CEO of Cablevision since October 1995. He became president of the company in June 1998. He is also owner of the New York Knicks of the NBA.
