Birth of video
Video cameras were made for broadcast media. In the 1900s image transmission was experimented with. John Logie Baird added to this with his invention of a “Nipkow disk,” a mechanical device that breaks an image into “scanlines” using a rotating disc with holes cut into it. -
Introducing electronic designs
In early television mechanical video images were being produced however, by the 1930s new all-electronic designs based on a cathode-ray video camera tube were accomplished by engineers Philo Farnsworth and Vladimir Zsworykin who replaced the mechanical variations with electron scanning technology. This soon became the standard for television industry and remained in wide use until the 1980s. -
Jvc and Panasonic
These companies developed the first self-contained large format video cassette tapes in the 1970s. This invention came later to consumer prominence in the 1980s via the video camcorder, a device that brought video recording into the mainstream. -
Analog to Digital
The transition from analog to digital video capture began in 1981 with the development of the Sony Mavica single-lens camera. This camera utilized a rotating magnetic disc, which was 2 inches in diameter and could record up to 50 still frames for playback or printing. -

Digital Video in Surveillance Technology
The late 1990s there was introduction of DVR devices, digital video recorders that used hard disk drives and similar storage devices to store large amounts of digital video information in a single home setup. This innovation quickly found an audience in surveillance and in niche markets such as “paranormal investigations.” In fact, crews of television programs like “Ghost Hunters” exposed many consumers’ to DVR setups. -
Going digital
Kodak released the first digital camera intended for professional use by photojournalists, followed by Nikon’s F-3, which included a 1.3-megapixel sensor. -
Modern Digital Cameras
In the early 2000s, Sony developed the first high definition digital video cameras. Today, a high-resolution digital video is no longer confined to the domain of the television studio. High-end professional digital video cameras are used for independent films, web series and hobbyist purposes. -

Present
Today, most smartphones include a webcam above the screen. While smaller, faster, and higher resolution than their peripheral predecessors, webcams still suffer from a wide and notably unimpressive range of qualities.
