Recent advances in exoplanet detection and characterization has told us that a new class of planet exists close to many stars. These planets have radii between that of the Earth and Neptune, yet periods of several to hundreds of days. Density measurements of some of these planets imply they must have voluminous H/He atmospheres. I will describe our current understanding for how these planets may have acquired their atmospheres and how their histories are dominated by, in some cases futile, attempts for them to retain these atmospheres so close to their parent stars.
