SMI to change reporting dates to better reflect advertisers’ media spending habits
The Standard Media Index has announced the reporting of media spending trends will be changed for future surveys, to reflect the industry’s changing spending patterns.
SMI”s public releases on media spending trends will now move to the end of the month to reflect agencies’ digital bookings being made later in the month compared to print and TV placements.

In Digital, SMI is not worth the .PDF it’s printed on. It doesn’t capture revenue from proprietary or 3rd party programmatic/ad tech platforms and usually reports ~50% variance in the revenues Publishers actually invoice their clients for. Dont think a date change will help with that.
