Thais spend around 16 hours per week on the internet, compared with just 10 hours watching TV, according to Ariya Banomyong, country manager for Google Thailand. However, TV media still accounts for 69% of Thai ad spending, while online ad revenue is only 3% of total ad spending, and mobile ads are less than 1%, according to the Digital Advertising Association of Thailand. The association said Thailand's online media spending should increase by 50% to 4.5 billion baht this year thanks to more widespread use of 3G. The sectors that spend the most on online ads are technology and mobile firms, automotive and tourism operators.
