Channels 4’s Married at First Sight has landed a new sponsorship deal with Colgate. This deal will mark the biggest and most integrated partnership of the show to date, including linear, digital, and social advertisement. Colgate’s Max White Ultra Range will take centre spotlight during the campaign, and the ad will air on E4, All4 and the spin-off MAFS: Afterparty. The creatives will feature close-ups of dazzling teeth from scenes included in the show, such as on the wedding day and commitment ceremony, to celebrate smiles all round.
