TV networks were ordered to replace their programmes with a prepared rolling state media programme for the next month, said national spokesman Lt Gen Sansern Kaewkamnerd.

All broadcasters must "link to a signal from the TV Pool for 30 days," he said.

As soon as the king's death was announced, domestic stations switched to monochrome pictures and video of the king throughout his 70-year reign.

Satellite channels -- including international news networks like the BBC, CNN and Al Jazeera -- were replaced later in the day with the same programming.

The move means most people cannot access independent news through their televisions.

Thai newspaper websites continue to publishing their own material but had ditched colour.

Internet access is unaffected. Major Thai language websites including Pantip.com chat forum, had gone entirely black and white.

The country mourns
Crown Prince Maha Vajiralongkorn, the son of late Thai king Bhumibol Adulyadej, is to be crowned as new Thai monarch.

However, the crown prince has asked for a delay before taking over the role.

The people of Thailand are mourning the death of King Bhumibol Adulyadej, the world's longest-reigning monarch, who died on Thursday aged 88.

An emotional crowd held a late-night vigil in Bangkok, and black-clad crowds are now returning to the streets.

The king's body will be taken to the city's Emerald Temple later on Friday. The official mourning will last a year.

Flags are to fly at half-mast for 30 days and the government has asked for people to wear black, and avoid "joyful events" during this period.

News websites have turned their pages black and white, while tributes have been paid by leaders around the world.
