Overnight household rating = the live+same day DVR overnight metered-market household rating from the top 56 Nielsen television markets. The 56 markets (out of 210 total) account for about 70% of the US TV-viewing population. The overnight household rating is the percentage of the households that were tuned-in in those markets. The share is the percentage of the households that were watching TV at the time.
Example: a 21 household rating with a 40% share means that on average 21% of all the households (in those 56 markets) were tuned-in and that 40% of the households watching TV at the time were tuned-in.
