This chapter focuses on traditional political ads in US elections, in particular those most often airing on broadcast television stations, investigating three key questions: Have traditional political ads reached a tipping point, as new technologies and voter targeting opportunities shift the resource allocation of campaigns? Do traditional political ads work in changing minds and mobilizing voters, and how might those opportunities for persuasion and mobilization change as media engagement diversifies? Finally, what is the issue content of traditional political ads, and how does the content vary across platforms? All told, despite fast-developing change in opportunities for political actors to reach voters, television advertising remains a critically important strategy for campaigns and their political allies.

A classical scenario for tipping is that a dynamical system experiences a slow parameter drift across a fold tipping point, caused by a run-away positive feedback loop. We study what happens if one turns around after one has crossed the threshold. We derive a simple criterion that relates how far the parameter exceeds the tipping threshold maximally and how long the parameter stays above the threshold to avoid tipping in an inverse-square law to observable properties of the dynamical system near the fold. For the case when the dynamical system is subject to stochastic forcing we give an approximation to the probability of tipping if a parameter changing in time reverses near the tipping point. The derived approximations are valid if the parameter change in time is sufficiently slow. We demonstrate for a higher-dimensional system, a model for the Indian summer monsoon, how numerically observed escape from the equilibrium converge to our asymptotic expressions. The inverse-square law between peak of the parameter forcing and the time the parameter spends above a given threshold is also visible in the level curves of equal probability when the system is subject to random disturbances.
