We consider the problem of spreading information in large random networks with small average degree. Randomized broadcasting is among the most fundamental and well-studied communication primitives in distributed computing, and has also applications in several other disciplines, like e.g. in mathematical theories of epidemics. A particularly popular example [1] is the maintenance of consistency in a distributed database, which is replicated at many hundreds or thousands of sites in a large, heterogeneous network. Obviously, efficient broadcasting algorithms are crucial in order to ensure that all copies of the database converge quickly and effectively to the same content.
