The sponsorship, negotiated between Starcom MediaVest and Granada Enterprises, represents the first above-the-line support for the brand since its launch last summer.
The alcoholic drink, a blend of Chardonnay, fruit and sparkling water, is aimed at 18- to 34-year-old women, with whom the previous series of Footballers' Wives performed well.
The third series will air from next month on ITV1. It will also make its debut on ITV2, which will screen the following week's episode immediately after the one shown on ITV1. Sponsorship credits are being created for Bliss by Granada's 3Sixty Media.
In another ITV deal, Walkers Snacks' Monster Munch brand is to sponsor ITV1's two-hour Saturday morning children's show Ministry of Mayhem for the next 12 months. The deal was negotiated between OMD Affinity and Carlton Sponsorship.
