The Big Ben chimes (known within ITN as "The Bongs") continue to be used during the headlines and all ITV News bulletins use a graphic based on the Westminster clock dial. Big Ben can also be heard striking the hour before some news bulletins on BBC Radio 4 (6 p.m. and midnight, plus 10 p.m. on Sundays) and the BBC World Service, a practice that began on 31 December 1923. The sound of the chimes is sent live from a microphone permanently installed in the tower and connected by line to Broadcasting House.

At the close of the polls for the 2010 general election the results of the national exit poll were projected onto the south side of the tower. On 27 July 2012, starting at 8:12 a.m, Big Ben chimed 30 times, to welcome in the London Olympic Games (i.e. the 30th Olympiad), which officially began that day

The clock has become a cultural symbol of the United Kingdom, particularly in the visual media. When a television or film-maker wishes to indicate a generic location in the country, a popular way to do so is to show an image of the tower, often with a red double-decker bus or black cab in the foreground.

In 2008 a survey of 2,000 people found that the tower was the most popular landmark in the United Kingdom. It has also been named as the most iconic film location in London.

Big Ben's dials and belfry are illuminated at night.

The sound of the clock chiming has also been used this way in audio media, but as the Westminster Quarters are heard from other clocks and other devices, the sound is by no means unique. Big Ben is a focal point of New Year celebrations in the United Kingdom, with radio and television stations airing its chimes to welcome the start of the New Year. To welcome in 2012, the clock tower was lit with fireworks that exploded at every toll of Big Ben.Similarly, on Remembrance Day, the chimes of Big Ben are broadcast to mark the 11th hour of the 11th day of the 11th month and the start of the two minutes' silence. Londoners who live an appropriate distance from the tower and Big Ben can, by means of listening to the chimes both live and on analogue radio, hear the bell strike thirteen times. This is possible because the electronically transmitted chimes arrive virtually instantaneously, while the "live" sound is delayed travelling through the air since the speed of sound is relatively slow.

Big Ben is the nickname for the Great Bell of the clock at the north end of the Palace of Westminster in London and is usually extended to refer to both the clock and the clock tower.The tower in which Big Ben is located is officially called the Elizabeth Tower; originally just the Clock Tower, it was renamed in 2012 for the Diamond Jubilee of Elizabeth II

Journalists during Queen Victoria's reign called it St Stephen's Tower. As MPs originally sat at St Stephen's Hall, these journalists referred to anything related to the House of Commons as news from "St. Stephens" (the Palace of Westminster contains a feature called St Stephen's Tower, a smaller tower over the public entrance).The usage persists in Welsh, where the Westminster district, and Parliament by extension, is known as San Steffan.

On 2 June 2012, The Daily Telegraph reported that 331 Members of Parliament, including senior members of all three main parties, supported a proposal to change the name from Clock Tower to Elizabeth Tower in tribute to Queen Elizabeth II in her diamond jubilee year. This was thought to be appropriate because the large west tower now known as Victoria Tower was renamed in tribute to Queen Victoria on her diamond jubilee.On 26 June 2012, the House of Commons confirmed that the name change could go ahead.The Prime Minister, David Cameron, announced the change of name on 12 September 2012 at the start of Prime Minister's Questions. The change was marked by a naming ceremony in which the Speaker of the House of Commons, John Bercow, unveiled a name plaque attached to the tower on the adjoining Speaker's Green.

The tower is designed in Pugin's celebrated Gothic Revival style, and is 315 feet (96.0 m) high. The bottom 200 feet (61.0 m) of the tower's structure consists of brickwork with sand-coloured Anston limestone cladding. The remainder of the tower's height is a framed spire of cast iron. The tower is founded on a 50 feet (15.2 m) square raft, made of 10 feet (3.0 m) thick concrete, at a depth of 13 feet (4.0 m) below ground level. The four clock dials are 180 feet (54.9 m) above ground. The interior volume of the tower is 164,200 cubic feet (4,650 cubic metres).

Despite being one of the world's most famous tourist attractions, the interior of the tower is not open to overseas visitors, though United Kingdom residents are able to arrange tours (well in advance) through their Member of Parliament. However, the tower currently has no lift, though one is planned, so those escorted must climb the 334 limestone stairs to the top.

Due to changes in ground conditions since construction, the tower leans slightly to the north-west, by roughly 230 millimetres (9.1 in) over 55 m height, giving an inclination of approximately 1/240. This includes a planned maximum of 22 mm increased tilt due to tunnelling for the Jubilee line extension.It leans by about 500 millimetres (20 in) at the finial. Experts believe the tower's lean will not be a problem for another 4,000 to 10,000 years. Due to thermal effects it oscillates annually by a few millimetres east and west.

Elizabeth Tower, previously called the Clock Tower but more popularly known as Big Ben, was raised as a part of Charles Barry's design for a new palace, after the old Palace of Westminster was largely destroyed by fire on the night of 16 October 1834.The new parliament was built in a neo-gothic style. Although Barry was the chief architect of the palace, he turned to Augustus Pugin for the design of the clock tower, which resembles earlier Pugin designs, including one for Scarisbrick Hall in Lancashire. The design for the tower was Pugin's last design before his final descent into madness and death, and Pugin himself wrote, at the time of Barry's last visit to him to collect the drawings: "I never worked so hard in my life for Mr Barry for tomorrow I render all the designs for finishing his bell tower & it is beautiful."
