Region by region, its 27 services from Arabic to Vietnamese have switched over to the state-of-the-art, multimedia building which brings together the BBC's national and global journalism operations.
Thursday's midday news at 1100 GMT was the final broadcast from the last working studio left in Bush House.
Newsreader Iain Purdon read the five-minute bulletin, leading off on the announcement of extra troops being deployed to the London Olympics.
"And now, after more than 70 years broadcasting to the world from Bush House in central London, this BBC news bulletin is the last to come from our Bush House studios," he said.
A recorded look-back at Bush House from outgoing BBC Director-General Mark Thompson was then played.
"This benign Tower of Babel, the scene of so many great broadcasting moments, and the home of so many great broadcasters over the years, is now silent; its corridors deserted; its studios empty," Thompson said.
Thompson said that through the Cold War to the complex 21st century, "Bush House became a unique icon of authority and trustworthiness in news to millions of listeners around the globe.
"Often, the World Service and the BBC's language services were the only source of reliable information available to listeners. In some countries, that's still largely true today.
"I'd like to pay tribute to all those who made Bush House such an enduring beacon of truth and objectivity in a troubled world, and I'd like to thank everyone who's tuned in over the years."
Signing off, Purdon then said: "So, the World Service and the news goes on; just not from here.
"From Bush House, that's the BBC news."
For many, broadcasts from Bush House have been a lifeline, with people living under oppressive regimes tuning in for impartial news about their country and the rest of the world.
Many have learnt English by tuning in, and Myanmar democracy icon Aung San Suu Kyi said it kept her going through her long years in detention.
At its peak, World Service broadcasts from Bush House were being made in 45 languages. Programmes have been transmitted in 68 different tongues. Niche services included Welsh for Patagonia.
An imposing, eight-storey building in Portland stone, Bush House sits between the Aldwych and Strand roads, flanked by the Indian and Australian high commissions and opposite the London School of Economics.
Built by US businessman Irving T. Bush, it opened in 1925 and was said to be the most expensive building in the world, costing some £2 million, or around £100 million ($155 million, 125 million euros) in today's money.
The BBC was only ever a tenant. Bush House has belonged to the Church of Wales and the Post Office and has been owned by Japanese firm Kato Kagaku since 1989.
The BBC's lease expires at the end of 2012. It is understood the building will continue as office space.
Auctioneers Peaker Pattinson are selling off its contents, starting this month.
The 3,000 lots include studio mixing desks, and pictures from the walls, including a framed photograph of Beatles legend Paul McCartney broadcasting to the Soviet Union in 1989.
Radio stations in eastern Europe, India and Pakistan have expressed an interest in buying some of the bigger studios, while turntables and reel-to-reel tape decks are attracting interest from club disc jockeys.
The World Service counts more than 160 million listeners across the globe.
Speaking after recording his insert, Thompson said it could be considered "the jewel in the BBC's crown".
"When you think of the voices and the sounds and all of the moments of world history which have been reported on and broadcast and discussed, there's an enormous weight of broadcasting history here," he said.
"This is still a sad and very memorable moment for us."
