At Twitter I worked on the B2B marketing team and one of our goals was to market Promoted Products. One way we decided to do this was to create a content calendar for clients, detailing all big TV and sporting events for the coming months, so they could plan out their promoted content.
The calendar folded out for a long view, or could be viewed as a booklet. It also contained stats around previous larger events, such as The Oscars, to encourage clients to get involved.
