Shell Quiz, known in its latest iteration as Shell Quiz on the Road, is a televised upper-secondary school quiz competition in Thailand which was broadcast from 1965 to 2009. The questions are given in English, and deal with a broad range of topics of knowledge, with the English language itself as a focus. The programme was sponsored by Shell Thailand. At the time of its last season, it was the longest-running television programme in the country. Production history The programme was organized by the Public Relations Department of Shell Thailand. It was first broadcast in 1965 on Thai TV Channel 4 (a.k.a. Channel 4 Bangkhunphrom), Thailand's first television channel and the precursor to Channel 9 and Modernine TV. The programme changed broadcasters many times, and was also broadcast on Channel 7, Channel 5 and Channel 11, the last of which broadcast the programme from 2001–2006.

The final season, the programme's forty-fourth overall, was broadcast in 2009. Format Prior to the 2007 season, the programme was conducted by a presenter and a native English-speaking quiz master, who presented the questions while the presenter offered explanations in Thai afterwards.

Teams of three students from forty-eight schools competed in a single-elimination tournament of one-on-one matches, except for the finals where all three teams met.
