I'm not sure if it is true or not, but wasn't the television footage of Adolf Hitler making a speech opening the 1936 Summer Olympics the first television transmission that was powerful enough to escape into outer space?
That said they wont have to wiat long to see that John Wayne saved the world and we're all OK.
at the end of the war when the bbc came back the presenter said " as i was saying before we were rudely intruppreted"
bit of an understatement, 40 million dead at least and europe and asia in ruins.
Well, before 1936 there was already a basic TV program. The first real TV show was made by Dénes von Mihály in Berlin 1928, but only in a very little circle. A year later the radio station Witzleben sent first test images. The first real and regularly TV program was made by the TV station Paul Nipkow in Berlin beginning in 1935 (and lasting until 1944). Even before, in 1926 the first electronic TV test image was sent in Japan. The Japanese also tried to build up a TV network but ww2 stopped all plans, like the Germans. In Germany the first TV station could only be seen by a few hundred TVs in and around Berlin.
So my guess is, that even before Hitler was opening the games of 1936 a picture was able to be broadcasted into the space. So this first program should be the first pictures to be seen from Earth. However as the opening of the games was the first big event broadcasted, it will be very impressing to Aliens.

In 1927 Baird transmitted a signal over 438 miles of telephone line between London and Glasgow. In 1928 Baird's company (Baird Television Development Company / Cinema Television) broadcast the first transatlantic television signal, between London and New York, and the first shore to ship transmission.
Happy Alex, I did not speak about TV signals, which were indeed many years before, but a TV show.
