The Office of the Communications Authority (OFCA) has commissioned NielsenIQ (Hong Kong) Limited (NIQ) to conduct an opinion survey on sound broadcasting services (Survey) from August to November 2026. The purpose of the Survey is to gauge public views on the sound broadcasting services of Hong Kong Commercial Broadcasting Company Limited (CRHK) and Metro Broadcast Corporation Limited (Metro).

To ensure that every household unit in Hong Kong has an equal chance of being selected for the Survey, sampled households are selected randomly. OFCA has issued notification letters via NIQ to the sampled households, inviting them to complete an online questionnaire. The selected household member can also call NIQ's service hotline (3755 3490) for making appointments for face-to-face or telephone interviews. A unique serial number is provided on the top left hand corner of each letter for the selected household to verify the authenticity of the Survey with the survey firm. If a household has not completed the online questionnaire or made an appointment for an interview, survey staff will visit the household and assist in completing the survey. The selected household member is expected to complete the questionnaire in around 20 minutes, depending on the actual circumstance.

All personal data collected in the Survey will be kept strictly confidential and will not be disclosed to any unauthorised third parties (including other government departments) in accordance with the Personal Data (Privacy) Ordinance (Cap. 486). All questionnaire data will only be used for aggregated statistical analyses and will be destroyed within three months after completion of the Survey.

To facilitate the selected households to verify the identity of the enumerators or to update information, in addition to NIQ's service hotline stated above, OFCA has also set up a designated hotline (2961 6292)¹ for enquiries by the selected households.

OFCA and NIQ will not call or send email or SMS message to households unless they have contacted OFCA and/or NIQ and left their contact details before, and will not embed hyperlinks in any unsolicited email or SMS message. OFCA and NIQ will not ask you to submit password in any telephone call, email or SMS message and survey staff will not ask for information about HKID, bank account or credit card.

We appeal for the support of all the selected households to actively participate in the Survey. The views collected from the selected households will be very important to OFCA in understanding the sound broadcasting services provided by CRHK and Metro.
