 In 2009, Bangkok University did a research on ‘The popularity of teenagers’. This data was collected to give parents and society to use this information as a consideration to decide on what action should they make to develop and help these teenagers. About 1000 teenagers age between 13 and 21 participated were asked on the research. 49.1 percent were boys and 50.9 percent were girls. The result shows that Ching Roi Ching Lan was the most popular game show for teenagers.
 The show has been modified many times due to the lack of popularity when it started. People's lifestyles at that time included going to bed very early, therefore night time shows were not so interesting. The name of the show has been changed seven times already, keeping the word ‘Ching Roi Ching Lan’ in every version.
