Logo history • Thai Thorathat's first logo depicts images of "Witchu Prapha Dhewi" (Thai: วิชชุประภาเทวี), female angels and thunderbolts, adorned with clouds and lightning within a circle, designed by the Fine Arts Department of the
Ministry of Education. • In 1977, the same time of change to MCOT organization, the logo evolved into a circle. The center is white circle; the upper part is four sections divided by the curve of spread spectrum signals; the bottom curve is yellow, and next three sections are in primary colors of light (red, green, and blue); the lower part is yellow with the Thai letters "อ.ส.ม.ท." which is the abbreviation of the organization. • In 2003, the time of change to MCOT PLC, the logo became circular gray lines intersecting like latitude and longitude, a purple figure which hides number 9 in the right part, and a gray curve in the upper part. Under this logo are the English letters "MCOT" in orange with gray border (convergence with Modernine TV, MCOT Modern Radio, and Thai News Agency)
Commercial breaks The logo is shown on commercial breaks and test transmissions.
Clocks The clock in
Thailand was not in colour until 1974. Originally the clock was based on the clock tower in
Bangkok in black and white. In 1974 the clock was yellow on blue.
