\nBelow are two graphs showing linear TV impressions for adults 18 and up (A18+) in 2019 and 2020. The charts clearly show a surge in impressions in 2020 that started around March 12, the day most people started to work from home in the US. This resulted in an increase in overall viewing in 2020, compared to the same period in 2019.\n\nUnlike the program-level impression count we have been displaying in our weekly analysis, here we show impressions at the spot-level (proxy for ad/commercial viewing).\n\n

The most striking daypart to examine is weekend viewing. In 2020, there were nearly 30% more impressions in weekend viewing, compared to the same period in 2019. This could be a result of a sudden shortage of weekend entertainment alternatives. **Without restaurants, nightclubs, bars, movie theaters, arenas and stadiums, television stands out as one of the few leisure options that can survive pandemic-related restrictions.**\n\nThe daypart that suffered the biggest decline was Early Morning, as many people probably didn't stick to their pre-pandemic morning routines once they started working from home.`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":102,"value":"$32","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":127,"value":"md`In conclusion, linear TV viewing in 2020 increased, relative to 2019, almost certainly as a result of the pandemic. This period has presented an extraordinary opportunity for advertisers to seize on a combination of declines in inventory prices and a surge in viewing to increase their share of voice, a reliable predictor of market share.
