Early radio broadcasting grew rapidly in the 1920s once manufacturers began selling affordable receivers for home use. Before this, radio had been used mainly for point-to-point communication, such as ship-to-shore messages, rather than for entertainment reaching a mass audience. Stations initially struggled to find a sustainable business model, and advertising-supported programming did not become the dominant approach in some markets until several years after regular broadcasts began. Governments in many countries eventually required stations to hold licenses and operate within assigned frequencies, partly to prevent signals from different broadcasters interfering with one another. Live music and drama were staples of early schedules, since recorded playback quality was initially considered too poor for broadcast, meaning most programmes had to be performed in real time in the studio.
