A conic bundle f: X\to S is a flat morphism of smooth varieties whose fibers are plane conics.
In this talk, I will first discuss application of Sarkisov program to the rationality problem of algebraic varieties having conic bundle structures.
Then I concentrate on some special, so-called tetragonal types of conic bundles, which lie on the "boundary" between birationally rigid and non-rigid ones and are especially interesting for this reason.
The second part of the talk is based on the joint work in progress with V. Shokurov.
