Perhaps the most studied example of non-critical string theory is that with two-dimensional target space. While clearly not of phenomenological interest, string theories in two-dimensions serve as important toy models. They allow one to probe interesting concepts which would be computationally intractable in a more realistic scenario. Additionally, these models often have fully non-perturbative descriptions in the form of the quantum mechanics of large matrices.
