Before their current seasons were suspended, NBA and NHL national telecasts were averaging $4 million and $477,000 per day, respectively, in advertising revenue according to TV ad measurement and attribution company iSpot.tv. Based on those averages, league broadcasters stand to lose out on $136 million and $11.4 million, respectively, in ad revenue if postponed regular-season dates are not rescheduled. Projected losses for other broadcasters of league games and events are based on advertising spend numbers during the most recently completed season or event.
