DESCRIPTION:Line-Intensity mapping (LIM) uses the integrated flux along th
 e line of sight as\ntracer of the LSS. Using relatively low-aperture teles
 copes\, it recovers radial information targeting known spectral lines disc
 arding the continuum emission\, which makes the experiments\ncheaper compa
 red with galaxy surveys. Mapping the intensity fluctuations of an array of
  lines\nfrom HI 21cm to optical-UV lines offers a unique opportunity to pr
 obe redshifts well beyond\nthe reach of other cosmological observations\, 
 access regimes that cannot be explored other-\nwise\, and exploit the enor
 mous potential of cross-correlations with other measurements. This\npromis
 es to deepen our understanding of various questions related to galaxy form
 ation and\nevolution\, cosmology\, and fundamental physics. In this talk I
  will cover the current status of\nLIM\, main measurements and the promise
 d potential for the future\, with focus on the\nnext steps that must be ta
 ken to bring this technique to full speed for precision cosmology.
