This paper analyzes a single television station’s choice of airing tune-ins (preview advertisements). I consider two consecutive programs located along a unit line.
If the sampling cost is sufficiently low, the unique perfect Bayesian equilibrium (PBE) exhibits no tune-ins. Otherwise, the unique PBE involves a tune-in unless the two programs are too dissimilar.
When the programs are also quality-differentiated, the willingness to air a tune-in, and thus to disclose location information, may be sufficient to signal high quality without any dissipative advertising.
