He later went on to establish Home Box Office (HBO) to cater to the burgeoning movie market. Dolan's entrepreneurial spirit led him to sell HBO and his cable service, allowing him to develop Cablevision, which provided television and internet services to countless households in the northeastern United States.

At the time of his passing, Forbes estimated Dolan's net worth at $5.4 billion.
