RoadShow (Chinese: 路訊通) is the first "Multi-Media on-Board" (MMOB) service system on transit vehicles in Hong Kong.

[2][3] RoadShow Holdings Ltd (路訊通控股有限公司) was listed on the Stock Exchange on 28 June 2001 SEHK: 888) and is currently a member of the TIH Group.

Bus Power Limited is engaged in the provision of media sales services for advertising on transit vehicle exteriors and interiors.

The Group's MMOB business includes installing, operating and maintaining equipment and LCD units in transit vehicles for the transmission of tailor-made programmes and advertisements, source programme content and marketing and selling advertising on the MMOB system.

Roadshow provides entertainment and advertisements to the passengers of public transit vehicles in Hong Kong.

The programmes are broadcast daily, to an audience of around 3 million, by a series of LCD monitors, each offering a 160° viewing angle, installed in over 4000 transit vehicles from KMB, Long Win Bus (a subsidiary of KMB), Citybus (Hong Kong) and AMS (maxicab).

The audio of the television broadcasts is delivered via 15 public speakers that line both sides of the passageways on the two decks with four-channel stereo systems.

The advertising on the transit vehicle exterior is produced from a high resolution vinyl which can be visible from distance by pedestrians.

The vinyl displays are able to withstand the rigors of cleaning and all types of weather, and they can also be removed without harming the paint on the transit vehicle through the use of a special adhesive.

RoadShow merchandising business sells a variety of commemorative items, bus models and souvenirs with the KMB logo.

RoadShow began operating on the Mainland in 2002 when it gained the rights to display advertising at the "Lamplight Rainbow" Tunnel on Huahai Road (淮海路) in Shanghai (上海).

It also began offering advertising agency services for the Guangzhou Metro mass transit system and outdoor media assets in other regions such as Tianjin(天津), Chengdu(成都) and Xi'an(西安).

TV drama highlights, weekly news summary, game show as well as infotainment programmes have been aired on RoadShow.

However, in dense urban areas with congested high-rise buildings, the satellite signals to the GPS receiver are often blocked and the accuracy of the results adversely affected.

It is a popular channel for companies to promote their products for different reasons: In addition to MMOB services, RoadShow also served as the agency in managing a number of outdoor advertisements on exterior and interior of buses and in bus shelter panels in Hong Kong.

RoadShow's website described bus television as "a highly effective multi-media advertising platform that pushes your products and services to reach a mass audience in a captive environment".

Members of the public and newspaper columnists have complained in the media about the problems of noise pollution, ubiquitous commercialism, exploitation of passengers' captive situation, abuse of public transport franchises, and the lack of options for passengers who prefer not to watch or listen to television broadcasts.

Prior to the establishment of HTB, what later became members of it lobbied against multi-media advertising on public transport under the ban of the Citizens Party.

It has been argued that its activities highlight the weak power of environmental or civic groups contra profit-making corporations.
