Voting is well underway for the three Grand Prix categories at the M&M Global Awards 2015, and the race could not be any closer.

Over 2,000 readers have already cast their vote for International Advertiser of the Year, International Media Brand of the Year and Programmatic Company of the Year.

The shortlist for each category has been decided by M&M Global’s editorial team, based on the companies’ performance over the past 12 months. The winners, however, will be decided by the international media community.

This week is your final opportunity to influence the result – the voting will close at 5pm Friday 7 August.

“It’s been an incredible response by the industry. The scores are so close and it’s credit to all of those who have been shortlisted that so many of their suppliers/clients are having their say,” said C Squared awards manager Graham Alexander.

“If you haven’t already, make sure you cast your vote by Friday, it’s going to be a thrilling finish and could make all the difference.”
