Waren Rauchzeichen früher wirklich ein Ding oder ist das eine Erfindung Hollywoods?

Some have used smoke signals, zb Navajo – but not to entertain themselves, but as a signal, zb when enemies appeared on the horizon or friends.

Otherwise, there were smoke signals in the world – e.g. on the watchtowers, which were raised on bead hurdles, in some areas on the Mediterranean, which were supposed to warn against pirates or – as a small wink from a past time – the imme rnoch existing smoke signals in the Paptwahl.
