Jeremy Vine is the current host of Crimewatch.
The programme - which reconstructs unsolved crimes in a bid to gather new information from the public - was relaunched in September 2016 with Jeremy Vine as host.
Daytime spin-off Crimewatch Roadshow will continue to be shown, the broadcaster said.
"We believe the successful Crimewatch Roadshow format in daytime is the best fit for the brand going forward and we will increase the number of episodes to make two series a year," a BBC spokesperson said.
"We are incredibly proud of Crimewatch and the great work it has done over the years and the work Crimewatch Roadshowwill continue to do, and this move will also allow us to create room for new innovative programmes in peak time on BBC One."
The show, first aired in 1984, has been influential in helping to solve a number of high-profile cases, including the murders of Jamie Bulger and Sarah Payne.
But there are a number of cases that remain a mystery, here are the five most infamous.
1. Murder of Jill Dando
The nation was plunged into shock when Crimewatch presenter Jill Dando, 37, was shot dead on the doorstep of her Fulham home on April 26, 1999. She had just returned from visiting her fiancé Alan Farthing.
A forensic study indicated that Dando had been shot by a bullet from a nine mm calibre semi-automatic pistol, with the gun pressed against her head at the moment of the shot.
Barry George was found guilty of her murder in 2001, but his conviction was quashed by the Court of Appeal in 2007.

In 1997, Crimewatch ran a report stating neighbours saw a white man, aged 30 to 40, about 5ft 10in with a mop of black hair, leaving the scene.
The case remains open.
Comment: Here's another angle on the murder of Jill Dando:
Popular TV presenter Jill Dando, who was shot dead outside her London home in 1999, tried to instigate inquiries into alleged paedophile activities within the BBC in the mid-1990s, it was claimed today, but "no-one wanted to know."
In an exclusive report on Sunday, Britain's Daily Star said that a source close to Ms Dando recalls her compiling a dossier of complaints about sexually abusive behaviour within the corporation and handing it over to bosses because she herself was a presenter rather than an investigative journalist.
"They gave it back. No-one wanted to know," said the source, herself a former BBC worker who asked not to be named.
2. Disappearance of Claudia Lawrence

The 35-year-old, who worked as a chef at the University of York, had spoken to her mother on the phone that night, giving no hint anything was wrong.
But Lawrence was never heard from again - leaving officers desperately probing into her past, her relationships and her work life in an effort to find her.
At one point, detectives believed she had been with 12 lovers over five years, with some of them married.
During the £1m investigation, a number of people were arrested over her disappearance - but none of the charges stuck.
And so her family has been left waiting, hoping they will one day have answers.
Other theories have been floated, with one that convicted killer Christopher Halliwell was involved in her disappearance.
The date was said to be significant to wannabe serial killer Halliwell - whose former garden in Swindon has been dug up by cops in the search for more victims.
The murderer abducted and murdered his second known victim on March 19 2011 - two years to the day that Lawrence vanished.
Police announced that they were scaling back the investigation into Claudia's disappearance, eight years after she first went missing.
Lawrence's family, who formed the Missing People's Choir, has vowed to keep searching with her mum Joan saying: "I realise the recent police team have worked very hard to try and get answers, and I know they feel people are still lying to them, but I can't allow Claudia's name to be forgotten.
"I will do everything in my power to ensure people keep searching for my beloved and precious daughter.
3. Suspected murder of Suzy Lamplugh

The man, who called himself 'Mr Kipper', was due to meet her outside a property in Fulham, London.
It is believed that Suzy, who lived in nearby Putney, was abducted and murdered but her body has never been found. She was officially declared dead in 1994.
Following her disappearance, police tested the DNA of 800 unidentified bodies and skeletal remains that matched Lamplugh's description.
Crimewatch appeals were broadcast in October 1986 and July 2000.
The Suzy Lamplugh Trust was established in 1986, to help people avoid becoming victims of aggression, and to offer counselling and support to relatives and friends of missing people.
4. Murder of Kate Bushell

Bushell set off from her home at 4.30pm on November 15, 1997. When she failed to come home, her parents notified the police.
A search located her body next to a field. Her throat had been cut.
Witnesses reported seeing a bloodstained man running away from the spot where her body was found.
The case remains unsolved despite a Crimewatch appeal in January 1998.
5. Murder of Jessie James

The teen and his friends were cycling across a park when numerous shots rang out.
The group broke apart but Jessie, trailing at the back, ended up cycling towards the gunman.
He was hit by three bullets at close range.
Jessie was not part of a gang and police fear his death was a case of mistaken identity.
A Crimewatch appeal was broadcast in December 2006.
Police have been worried about the lack of witnesses coming forward, possibly due to fear of repercussions.
