An email from Samba TV went out on 4/16. Samba is an Automatic Content Recognition (ACR) company. Samba measures TV viewership from TV's and mobile devices. Here is their findings during the COVID Pandemic
1 Massive migration away from linear moving to CTV & OTT. While time spent watching Across the board is up, it is up disproportionately in favor of streaming
2, This disproportionate growth in CTV | OTT is leading to the total reach of linear TV shrinking, while frequency is spiking. That finding makes sense, it's just medium math reach X frequency equals groups. If reach is shrinking the only thing that can go up is frequency.
CTV I OTT always getting better.
