The document discusses two UK regulatory bodies - the Advertising Standards Authority (ASA) and Ofcom. The ASA regulates advertising across various media like print, TV, radio and internet. It handles complaints and can order ads to be withdrawn if found breaching advertising codes. Ofcom regulates TV, radio, telecoms and monitors compliance with various content codes. Two case studies of ASA rulings on alcohol and car ads are provided, with one ad upheld as inappropriate and the other given no further action.
