At least in the US, it's been exactly this way for at least the last 20-30 years. 20 years ago was 2003, if you showed me this photo and told me it was from the turn of the millennium I wouldn't bat an eye. The 90s was crazy with all these fast brands and snacks. Everyone's freezer was filled with totinos pizza rolls.
Arguably longer to be honest. I can't remember a time where frozen microwave junk food didn't dominate the grocery stores and TV advertising. I wouldn't hesitate to believe an argument that it's been like this since the early 70s but assume it happened sometime in the 80s when the stay-at-home housewife transitioned to the career-focused woman.
I somewhat agree but your time scale is way off.
