Also having climbed to quite a nimble state, the vacuum had around the same time arrived at a commercially affordable and suitably domestic form, of course now mechanised as opposed to the earlier mercury based drop systems. The function had shifted from that of the contained vacuum, as found in tubes, to the home, a tool for everyday cleaning.  
Not having endured to present day, the machines of the time had many different attachments, one of which was a dispenser for insecticide. This was however intended for domestic use and had not been designed for the outdoor spraying of herbicides.
Generally unhealthy, the herbicides manufactured have since evolved from their semi-poisonous and carcinogenic state, a move that led to the dumping of thousands of barrels of the older compound in lakes not far from this city. This would have many negative effects on the surrounding population and environment.
 But sound was great, music was abundant and the formats for carrying sound were steadily developing. Almost in return to the root of the company we see a development in many different areas.
The man who stream lined much of the incandescent light bulb industry had also been involved in the recording and playback of sound. He had devised a basic inscription technique, translating difference in sound pressure to wax in order to record sound. The recording time of such a wax cylinder was around two minutes. After quite some work towards the invention he had put it on hold in order to work on the incandescent bulb.
 The cylinder evolved through the record and around 60 years after the cylinders first production the Company patented, standardised and released the first compact audio-cassette . They used high-quality polyester tape produced by a company in their neighbouring country. The next year in the country of the man who perfected the phonographic principle, sales began of a dictation machine that used the new cassette tape. The consumer's demand for blank tape used for personal music-recording was unanticipated by the company and industry in general. Demand was huge and the profits gained from sales grew exponentially.  
The means by which to amplify sound had existed for radio long before the birth of the cassette. Like the mini watt radio tube, the company had also been manufacturing various valve tubes for amplification of audio signal, as well as the amplifiers as units themselves.
The constant reinvestment of profit into scientific research of the company enabled the invention of many later products like the videocassette recorder, and the “ image record”, a disc read by laser. This was later to arrive at the compact disc, a digital means of storing numerous documents, video and sound alike in the form of data. This was to revolutionise the means by which people would work, play and share.
