[InsanelyIncredibly]

I'm slightly intrigued as to how some media outlets have obtained a fuller version of the interrupted broadcast, given that not all of it seemed to make it to air?

It is interesting - the version that made it to the air stopped at the phrase "Perhaps Polish media (TVP) have been taken over" before a buffer stepped in (as on video below). I guess someone had to give it to them, presumably former leadership (as it benefits them more than the new heads of TVP).

(just a note: the guy who appears here was not a host of this episode of Agrobiznes (news for farmers) and he crashed into the show to bring in 'special edition of Wiadomości [main news broadcast]'; this is most likely the last broadcast coming from the last leadership that as of now still is in control of news HQ (Powstańców Warszawy Sq.), while current news broadcasts come from Woronicza St. HQ which was taken over by new leadership).
