The business sentiment by 2011's end will be a mixed bag—combining the contraction of 2009 and the slight expansion of 2010—Sir Martin Sorrell, CEO of WPP Group, the world’s largest advertising agency told CNBC Tuesday.
“There will be some caution, but people are going to have to focused on growth. Otherwise they are not going to have a good story to tell on CNBC,” said Sorrell.
WPP, which has 138,000 employees in 2,400 offices in 107 countries, reported new business and strong billings into the first seven months of the year, lead by a robust US comeback.
