LenseNet

LenseNet was the world's first web browser developed by Theorysonic in 1983 which came bundled with the TS-OS 6. It was discontinued and replaced by Theorynet in 1985. When it was released, LenseNet was the sole web browser in existence.

The development of LenseNet began in 1981.

History
LenseNet was developed by the Vlokozu Union government when they heard of France's Minitel. The system used by LenseNet was picked by Swiss researchers at CERN over Minitel, the UK's Prestel, and Canada's Telidon in the late 90s, because it had more features, and didn't require a telephone line.
