Hannity, 60, had spearheaded Fox News’s prime-time programs for 25 consecutive years, six months, and 15 days when he broke King's record, according to a Fox News statement.
"Sean's authenticity and insightful commentary have created one of the most enduring connections with our audience, and it's been an honor to watch him over the years," Fox News Media CEO Suzanne Scott said.
Hannity joined Fox News in 1996, the same year the channel launched.
"A Fox News original, he has helped innovate the industry, and we are incredibly proud of his extraordinary success," Scott said. Hannity praised Fox News and his viewers for the time he had spent hosting in a prime-time slot.
