that it did not service the production team any longer. Also, two video screens were installed – one that displays the current question in play, and another that displays the contestant's cumulative total and progress during the game. In September 2012, the redesigned set was improved with a modernised look and feel, in order to take into account the show's transition to high-definition broadcasting, which had just come about the previous year. The two video screens were replaced with two larger ones, having twice as many projectors as the previous screens; the previous contestant podium was replaced with a new one; and light-emitting diode (LED) technology was integrated into the lighting system to give the lights more vivid colours and the set and gameplay experience a more intimate feel. Catchphrase Millionaire has made catchphrases out of several lines used on the show. The most well-known of these catchphrases is the host's question "Is that your final answer?", asked whenever a contestant's answer needs to be verified. The question is asked because the rules require that the contestants must clearly indicate their choices before they are made official, the nature of the game allowing them to ponder the options before committing to an answer. Regularly on tier-three questions (and sometimes on tier-two), a dramatic pause occurs between the contestant's statement of their answer and the host's acknowledgement of whether or not it is correct. Many parodies of Millionaire have capitalised on the "final answer" catchphrase. In the United States, the phrase was popularised by Philbin during his tenure as the host of that country's version, to the extent that TV Land listed it in its special 100 Greatest TV Quotes and Catchphrases, which aired in 2006. On the Australian versions, McGuire replaces the phrase with "Lock it in?"; likewise, the hosts of the Indian version have used varying "lock" catchphrases. There are also a number of other non-English versions of Millionaire where the host does not ask "[Is that your] final answer?" or a literal translation thereof. Besides the "final answer" question, other catchphrases used on the show include the contestants' requests to use lifelines, such as "I'd like to phone a friend"; and a line that Tarrant spoke whenever a contestant was struggling with a particular question, "Some questions are only easy if you know the answer."
