The world's largest advertising group WPP raised its full-year sales outlook on Wednesday, saying strong client demand had helped it to buck the gloomy mood gripping the global economy. Tech giant Google reported its first quarterly miss of the pandemic on Tuesday, adding to the sense that the invasion of Ukraine, soaring inflation and product shortages had started to throttle the recovery from COVID-19. Britain's WPP, owner of the Ogilvy, Grey and GroupM agencies, said that while customers were cautious about the growing pressure on consumer budgets they had not cut back their ad spend. It mentioned Coca-Cola as one client that had provided a strong impact. Inflation can also have a positive impact on advertising budgets as businesses need to produce marketing campaigns to explain and support their price rises. "We had a good year last year and that momentum has very much continued into the beginning of this year," Chief Executive Mark Read told Reuters.
