Here's why Dolan's not likely to be going anywhere soon:

STILL, there had been some industry speculation that Mr. Dolan might try to marshal board support to dismiss his son and that the family might come apart as a result. That is what happened in the vicious battle over Dart Drug in 1993, when Herbert Haft fired his son Robert, the chief executive, and replaced him with another child, Ronald, who had never run a public company and with whom the father began feuding immediately.

The wife of the elder Mr. Haft, Gloria, sided with Robert as the family fighting intensified. (She later divorced her husband.) By the time the battle ended in 1997, no Haft was involved in the business that the family had founded 50 years earlier.

But such public feuds are still relatively rare at family-run corporations. Even the elder Mr. Dolan recently pointed to the fact that under his son Cablevision's results have been better each year. The company's stock has gone to about $27 a share from $7 since James Dolan took over as chief executive.
