 A sparse bound is a novel method to bound a bilinear form. Such a bound gives effortless weighted inequalities, which are also easy to quantify.  The range of forms which admit a sparse bound is broad.  This short survey of the subject will include the case of spherical averages, which has a remarkably easy proof.
