- The Audience Appreciation Index (AI) is an indicator measured from 0 to 100 of the public's appreciation for a television or radio programme, or broadcast service, in the United Kingdom. Until 2002, the AI of a programme was calculated by the Broadcasters' Audience Research Board (BARB), the organisation that compiles television ratings for the major broadcasters and advertisers in the UK. Currently the AI is produced as part of an online Television Appreciation Survey, on behalf of the BBC Audience Research Unit, by GfK NOP. As the individual ratings that produce the AI of a programme are recorded online the day after broadcast, the resulting score is usually available two days after broadcast, though these scores are not generally made public by the BBC. The AI is considered especially useful for assessing the level of appreciation by viewers for programmes made for small or specialist audiences. If a television programme has performed only passably in the ratings, yet achieves a high AI, it can help to determine whether the programme should be recommissioned. On average, programmes aired on the BBC's four main television channels (BBC One, BBC Two, BBC Three and BBC Four) for the period April–June 2013 received an AI rating of 82.3 and radio programmes received an AI rating of 79.9. The average AI for a drama programme on UK television channels BBC One and ITV1 was reported, in 2009, to be 84. Programmes with specialist appeal will often score higher ratings. Internal guidance to BBC production staff is that an AI of 85 or over is to be considered excellent, over 90 is exceptional, 60 or less is poor, and less than 55 is very poor. Sometimes a programme will not garner an AI, as the response for that programme may have been too small. Nor is the AI a conclusive measure; while it is valuable for comparisons within a particular programme category, comparisons between the AIs of different programme types (e.g. dramas with quiz shows) carry no weight. AI scores in the 90s are less common, though this is less the case for niche, targeted programming that attracts a limited number of viewers, such US imports on smaller channels (such as Sky1), or for specialist programmes, or some very popular dramas. The highest recorded score until the end of 2009 was 97 for a US import on Sky1. Scores lower than 30 are very rare, though some party political broadcasts have received AI scores in the 20s. One criticism of the more general value of AI scores is that audiences tend to watch those shows they like, or expect to like, and so will tend to score them well. (en)

- 观众欣赏指数（Audience Appreciation Index，AI）是在英国用于确定公众对电视、广播节目或广播服务评价的指标，满分为100。 在2002年之前，AI指标由为英国主要电视台和广告商统计收视率的BARB计算。现在，AI由GfK NOP为英国广播公司观众研究部通过网络进行调查。 AI在节目播出的一天后调查，结果通常在节目播出两天后公布，但BBC通常不被公开这些数据。对于观众面窄和专业节目来说，AI尤为有用。如果一个节目在收视率上一般，AI是否高会帮助确定这个节目能继续。 BBC电视节目（至2011年6月）的平均AI评价为82，广播节目为80。据报，2009年英国广播公司第一台和ITV1戏剧节目的平均AI为84。专业节目的AI往往较高。BBC制作人员的内部指引是，85或更高则被认为是“很棒”，超过90是少见的，低于60是烂，低于55是很烂。有时一个节目不会得到AI，原因是这个节目太小。AI不是决定性的评价标准，可用它在同类节目间做比较，不同类型的节目（比如戏剧和问答节目） 间做比较是没有意义的。 超过90的AI是不常见的，通常在吸引有限观众的节目中出现，如小频道（如Sky1）引进的美国节目、专业节目和一些非常受欢迎的戏剧。2009年末前AI最高的节目是一个Sky1引进的美国节目，为97。低于30的节目很少，一些政党政治广播会低于20。一个对AI的评价是，观众会给自己喜欢的，或期待喜欢的节目更好的评价。 (zh)
