The BBC World Service broadcast from Bush House for the final time on 12 July 2012, after more than 70 years in the building. When it opened in 1925, it was considered the most expensive building in the world, with a cost estimated at £2m. The building has been the location of numerous historic moments, including King George V addressing the British Empire from the building in 1932.

历时70多年后，2012年7月12日英国国际广播电台从布什大厦完成了最后一次播音。1925年布什大厦刚刚对外开放时，它被认为是当时世界上最昂贵的大楼，建筑成本被估为两百万英镑。这幢大厦曾见证过无数次历史性时刻，其中包括英国国王乔治五世对大英帝国1932年的演讲就是从这里播出的。
