We give several new characterizations of the dual of the dyadic Hardy space H1,d(T2)H^{1,d}(\mathbb{T}^2), the so-called dyadic BMO space in two variables and denoted {\mathrm{BMO}}^{\mathit d}_{prod}}. These include characterizations in terms of Haar multipliers, in terms of the ``symmetrised paraproduct'' Λb\Lambda_b, in terms of the rectangular BMO norms of the iterated ``sweeps'', and in terms of nested commutators with dyadic martingale transforms. We further explore the connection between {\mathrm{BMO}}^{\mathit d}_{prod}} and John-Nirenberg type inequalities, and study a scale of rectangular BMO spaces.
