Since its creation in 1998, it has been normally held by the pro-democracy camp, with the interruption from 2008 to 2012, where the seat was held by pro-Beijing Samson Tam who defeated pro-democracy candidate Charles Mok by 35 votes with the help of the Internet Professional Association (iProA), a pro-Beijing IT association.

The Information Technology constituency was composed of individuals who are members of relevant associations such as the Hong Kong Computer Society, and Institute of Electrical and Electronics Engineers and corporate members of organisations such as the Hong Kong Information Technology Federation, Hong Kong Wireless Technology Industry and Society of Hong Kong External Telecommunications Services Providers who are entitled to vote at general meetings, as well as some other corporations with certain licences granted by the Telecommunication Authority.

Incumbent legislator Charles Mok questioned whether pro-Beijing forces were getting people to sign up.
