How I Met Your Mother.

A show that a took up so much collective human watchtime and had ~zero enduring cultural impact

this doesn’t feel too uncommon in the primary network tv era tbh

see: two and a half men, grey’s anatomy, however many CSI/NCIS/whatever variations there were, etc

extremely blessed highly favored always grateful

Two and a half men has the cultural impact of crashing Charlie sheen out

There was also a lot of really good network TV especially comedy on in that time frame though 

Modern family 
Parks and rec
30 rock 

Then a year or two later you got 

Don't trust the b in apartment 23
Two broke girls


There were some bangers but so much trash I do agree on that
