Due to the introduction of the Television Without Frontiers Directive (1989), tobacco advertising and sponsorship on television were banned within the European Union from 1991. Formula One faced a major threat regarding races in its historical European heartland. Due to these political and legislative circumstances, the Grand Prix at Spa was left out of the 2003 calendar as a response to the internal tobacco legislation in Belgium. The event was tagged as a world class event within the national senate, and thus it was saved for the 2004 Formula One season. The final Bus Stop chicane was reprofiled for 2004 with an additional sweep to the right.
