When Laura Ingraham debuts a 10 p.m. show on Fox News next month, the launch will cap a remarkable stretch of programming instability at the network. Five of Fox News's six evening time slots will have changed at least once since September 2016.

Just try to follow this chain of events:

Ingraham will replace Sean Hannity at 10 p.m., who will replace “The Five” at 9 p.m., which will replace “The Fox News Specialists” at 5 p.m., which previously replaced “The Five,” which had moved to 9 p.m. to replace Tucker Carlson, who replaced Megyn Kelly at 9 p.m. before he replaced Bill O'Reilly at 8 p.m. but after he replaced Greta Van Susteren at 7 p.m. and subsequently turned over the 7 p.m. slot to Martha MacCallum.

Got all that? No? Try this graphic, instead:

The one constant over the past year has been Bret Baier's “Special Report” at 6 p.m.

Several of Fox News's moves have been directly or indirectly connected to allegations of sexual misconduct. Van Susteren, who initially supported Roger Ailes when he was accused of sexual harassment by former Fox News anchor Gretchen Carlson last year, left the network shortly after its longtime chairman was forced to resign. Roughly two dozen women had come forward with stories similar to Carlson's, including Kelly, who endured criticism from O'Reilly for speaking out and bolted in January.

Then, in April, O'Reilly was ousted amid his own sexual harassment allegations. And this month, Fox News cut ties with Eric Bolling, who was briefly the centerpiece of the “Specialists” show, after multiple female colleagues told HuffPost that he had sent them pictures of male genitalia.

Frequent lineup changes are unusual at Fox News, where viewers had been able to tune in to the same stars at the same times, year after year. Competitors have tried to take advantage of the volatility, with some success. MSNBC's Rachel Maddow, who recently marked nine years at 9 p.m., now draws the largest prime-time audience on a semiregular basis — including in the month of August — after years of consistently trailing O'Reilly and Kelly.

But Carlson scores his share of ratings wins, too, and Fox News remains dominant, overall — the most-watched cable news channel for 62 straight quarters.

The network's latest moves set up a head-to-head battle between Hannity and Maddow at 9 p.m., which would be an intriguing contest even if Hannity were not encouraging advertisers to boycott Maddow's show.

Ingraham will be pitted against MSNBC's Lawrence O'Donnell and CNN's Don Lemon, both of whom are favorite Fox News targets. Ingraham is a longtime Fox News contributor and fill-in host, so her transition figures to be pretty natural.

In a news release Thursday, Fox News’s president of programming, Suzanne Scott, said the network is “delighted to unveil this new prime-time schedule for both our current and future generation of loyal FNC fans.”

Perhaps that future generation can look forward to watching the same hosts at the same times for a while.
