Before the communism fell, the main news program on Polish tv was called Dziennik. It went on air every day at 19.30, after children’s programs that run 15 minutes in advance before the news. It was covering world events from a communistic perspective.
Today the news is called Wiadomosci, but this main news program is still aired at 19.30 on TVP1 every day, which is the main national tv channel in Poland.
This clip on YouTube seems to be from a program about Dziennik. Thanks to BasicMasterReloaded, which uploaded this as this have deep historic roots for sure.
