The younger generation always has been, and always will be, totally so much worse than the older generation.
In the US in the past few decades? Yes. Absolutely.
Going back to at least the 1990s a kid could watch cartoons before school and then for several hours afterwards on broadcast channels.
For households with basic cable there were also very popular networks running all day full of children’s content (Disney Channel, Nickelodeon etc.)
These networks were very successful because they excelled at grabbing attention and keeping eyeballs on screens. For one example of these corners of hyper-popular children’s entertainment that kept kids glued to screens before YouTube just look at the works of Dan Schneider. https://en.m.wikipedia.org/wiki/Dan_Schneider
I can remember visiting friends houses where there would be multiple television sets (including tv sets in bedrooms) and television would always be turned on, even if no one was watching it. It was like a constant low level background noise. I found it strange but it was normal to them, they were used to eating dinner or playing with legos etc with tv constantly on in the background.
Depends on your era. The 90's gave us Beavis and Butthead, Southpark, Ren & Stimpy and the Power Rangers. It gave us XTREME!!! everything. It gave us Mortal Kombat and AOL. There was a lot of parental concern about the stuff the "kids these days" were consuming.
The 80's gave us Transformers or Voltron. It gave us MTV and the rise of Nickelodeon. It gave us GI Joe cartoons, He-Man, Teenage Mutant Ninja Turtles and an endless supply of toys imported from japan and accompanied by 30 minute commercials for those toys (see also Transformers, Voltron, He-Man etc). There was a lot of parental concern about the stuff the "kids these days" were consuming, heck they got the federal government involved they were so concerned.
Bugs Bunny and Looney Tunes had people concerned for its mindless violence and effect on kids. Remember that Mr. Rogers started his show (and pitched continued funding for PBS to congress) on the concerns that TV was just mindless dreck rotting children's brains.
Start going much earlier than that and the ability of entertainment to be just broadcast into your life and home reduces considerably, but I imagine parents in the 1800's also had plenty of concerns about various mindless entertainment drivel that was luring their children off the godly paths.
