The National Broadcasting System's User Survey, June 1985

This dataset is derived from the “The National Broadcasting System's User Survey, June 1985” that was conducted by Statistics Norway (SSB) on assignment from the Norwegian Broadcasting Corporation (NRK). The survey from June 1985 was included as a part of Statistics Norway's listener -and viewer surveys for the Norwegian Broadcasting Corporation. Statistics Norway conducted from 1967 to 1977 annual general radio and television surveys on behalf of the Norwegian Broadcasting Corporation (NRK). Several special surveys were conducted in the period 1978 to 1985, and surveys of a more general character were only conducted in 1980 and 1983. From 1985 a new arrangement of three general surveys per year was put to use. The reason for this alteration was the new media situation in the 1980ties that provided opportunities to choose between more and more channels on both radio and television.

The most important purpose of the new survey arrangement was to provide data concerning:
- Changes in listener and viewer patterns over time
- Variations in listener and viewer patterns in different seasons
- Use and choice of different channels and program offers in radio and television
- How people listen to radio and watch television
- Access to radio and television sets and equipment that are used in connection to radio and television apparatuses.

In addition to this, the Norwegian Broadcasting Corporation wished to ask questions concerning people's opinions about different aspects of Norwegian Broadcasting Corporation program operations and concerning certain programs or program types. The purpose was to conduct surveys that could give grounds for the Norwegian Broadcasting Corporations work in creating an offer of programs that listeners and viewers could benefit from, and that could contribute to illustrate the part radio and television play in people's lives.

Three general surveys were conducted in 1985, in February, June and in September/October. This file consists of data from the June survey. NSD does not have access to data from the February survey.

A gross sample of about 1500 interviewees was selected. These were interviewed in 7 groups about listener and viewer habits yesterday and the day before yesterday. The net sample amounted to 1136 interviewees.

When mapping out time consumption, 24 hours was divided into fixed 10 minutes time intervals. Then activities for each time unit were registered, either it was spent listening to the radio, watching TV or doing other things. As a result, the two days could be put together, and one could let the interviewees be represented with two days in order to study time consumption. The number of units (days) was twice as much as the number of respondents and each person were therefore included two times in this dataset. This was done in order to include the interviewees answer for both days of programs in the same variable. This means that for instance the variable v156 “Hørte på radio 06.05 - KANALKODE” contains information about what the interviewee listened to on the radio at 06.05 o'clock on both days, both yesterday and the day before.

本数据集源自挪威统计总局（Statistics Norway, SSB）受挪威广播公司（Norwegian Broadcasting Corporation, NRK）委托开展的《1985年6月全国广播系统用户调查》。该1985年6月调查系挪威统计总局为挪威广播公司开展的听众与观众调查项目的组成部分。

挪威统计总局曾于1967年至1977年间代表挪威广播公司开展年度通用广播与电视调查。1978年至1985年间，该局开展了多项专项调查，仅在1980年与1983年实施过通用性质的全国性调查。自1985年起，挪威统计总局启用了每年三次通用调查的新方案，此次调整的动因是20世纪80年代的新媒体环境——公众可选择的广播、电视频道数量日益增多。

新调查方案的核心目标是提供以下维度的相关数据：
- 听众与观众收视收听习惯随时间的变化趋势
- 不同季节听众与观众收视收听习惯的差异
- 广播与电视领域不同频道及节目内容的使用与选择情况
- 公众收听广播与收看电视的具体行为方式
- 与广播、电视设备配套使用的接收器材及相关附属设备的拥有情况

此外，挪威广播公司还希望通过本次调查收集公众对其节目运营各维度的看法，以及针对特定节目或节目类型的评价。本次调查的核心宗旨，是为挪威广播公司优化节目编排、打造契合受众需求的节目内容提供数据支撑，同时阐明广播与电视在公众日常生活中扮演的角色。

1985年共开展三次通用调查，分别于2月、6月及9月/10月实施。本数据集包含6月调查的相关数据，NSD无法获取2月调查的原始数据。

本次调查的总抽样样本约含1500名受访者，研究人员按照7个分组对受访者近两日（昨日与前日）的收视收听习惯进行了访谈。最终有效样本量为1136名受访者。

在统计时长占用情况时，研究人员将24小时划分为固定的10分钟时间区间，随后记录每个时间区间内受访者的活动类型：收听广播、收看电视，或进行其他活动。由此可将两日的调研数据进行整合，使每位受访者以两日的维度被纳入样本，以开展收视收听时长的相关分析。此时样本的时间单元（天数）为受访者人数的两倍，因此每位受访者在本数据集中会被记录两次，以完整涵盖其两日的节目收听收看情况。例如，变量v156"Hørte på radio 06.05 - KANALKODE"包含了受访者两日（昨日与前日）6点05分收听广播的频道相关信息。
