Not sarcasm, but not reality
You sound like someone from the UK, but maybe you're just an Ameriphobe. Your inaccurate synopsis of both television and navigation system demonstrates that. Yes, the 1936 BBC event was the first public broadcast, but it was with a system that was technically and commercially invalid. The US (Farnsworth's 525 line) system that was adopted here in 1941 had been in limited use since 1936. That became the NTSC standard. The Russians developed the 625 line standard, which Europe standardized later as the CCIR system. But, the point is that there were actually numerous attempts at making a valid commercial TV system, and the US was the first to accomplish that. On your other point, the Decca Navigation System was designed by an American (William J O'brien) and sold to the British Decca record company in 1941. It was a nice low level navigation system more useful to ships than to aircraft. As aircraft high level capabilities increased it became pretty worthless. Your claim that mid-air crashes were because of the considerably better American system is just pure hogwash.
