While political broadcasting never seems to be totally off the airwaves, the 2020 election season is about to click into high gear, with the window for lowest unit rates to begin on December 20 for advertising sales in connection with the January Iowa caucuses. That means that when broadcasters sell time to candidates for ads to run in Iowa, they must sell them at the lowest rate that they charge commercial advertisers for the same class of advertising time running during the same time period. For more on issues in computing lowest unit rates, see our articles here, here and here (this last article dealing with the issues of package plans and how to determine the rates applicable to spots in such plans), and our Political Broadcasting Guide, here.
The beginning of the LUR (or LUC for “lowest unit charge”) window in Iowa is but the first of a rapid many political windows that will be opening across the country as the presidential primaries move across the country. These windows open 45 days before the primary election (or caucus, in states where there is a caucus system that is open to the public for the selection of candidates) and 60 days before general elections. For the Presidential election, New Hampshire of course comes next, with their LUR window opening on December 28. January will bring the opening of a slew of LUR windows for states with primaries and caucuses in late February and early March, including all of the Super Tuesday states. But it is important to remember that these are not the only LUR windows that broadcasters will have to observe in 2020.
