There has been plenty of recent interest in deformations of two-dimensional QFTs constructed from bilinears of conserved currents. On the one hand, these deformations are exactly solvable; on the other, they appear to lead to a new type of ultraviolet behaviour in QFT, and also have very interesting applications in holography. I will concentrate on the two best studied such deformations: the TTbar and JTbar deformation of two-dimensional CFTs, and discuss their similarities and differences in what regards the spectrum, various observables, and holography
