the brady bunch first was on tv in 1969. the children from the brady bunch show are in their 60s now. i am starting to think that kirk candace cameron are probably close friends with them 

candace has been on television since 1982

tv started in 1948  tbn started in 1973    kirk cameron has been on tv since 1985

kirk cameron works for tbn 

television started in 1948 basically in the u.s.  tbn started in 1973

it is not easy to explain. there are gen z people that are crying because their parents got to live through the 80s 90s and be a young adult in the 2000s. this gen z guy was crying saying "how does it feel to live my dream , mom".  if television started in 1920s for europe and 1939/1948 for the u.s., and people are already crying about not being able to participate in the 80s 90s, from 1948 that that was only 30, 40 years that entertainment was interesting enough that people wish they were a part of it

this has only been around for 100 years. television has only been around since the 1920's 

most people today were born in the 1900s

the first movies were in 1895 

it is not really that easy to explain, but i dont think there is another country in the world that lets children grow up on camera .
