The advertiser frequently got top billing over the star, as in "The Pepsodent Show starring Bob Hope" or "The Chase and Sanborn Hour starring Edgar Bergen and Charlie McCarthy." If a sponsor dropped an otherwise popular show, the network might choose to continue producing the show itself while it sought a new producer/sponsor, and in the meantime sell individual commercial slots in the show to any sponsors interested.
