  The phenomenon of beamstrahlung can give rise to potentially dangerous
hadronic backgrounds due to minjet production at the future linear colliders as
well as at the \gamma \gamma colliders that are under consideration. In this
talk I will review briefly the current estimates of these backgrounds and
predictions of the eikonalised minijet model for \siginel. I end by pointing
out issues that need to be studied in more detail to firm up our estimates of
these backgrounds.
