The survey by global branding authority Superbrands put the agencies just two positions apart, in 365th and 367th respectively. The ranking of 500 brands was released this week.
The next ranked agencies were ‘Citigate' (418th), Bell Pottinger (448th), Burson-Marsteller (462nd) and Brunswick Group (497th).
‘It is the first time we have used consumer votes, as well as experts, to help determine the outcome,' Superbrands chairman Stephen Cheliotis told PRWeek.
The BBC, Microsoft and BA topped the poll overall.
