Abstract
Standard media economics models imply that increased platform com-
petition decreases ad levels and that mergers reduce per-viewer ad prices.
The empirical evidence, however, is mixed. We attribute the theoretical
predictions to the combined assumptions that there is no advertising con-
gestion and that viewers single-home. Allowing for crowding in viewer
attention spans for ads may reverse standard results, as does allowing
viewers to multi-home.
