Gary Thuerk was the world’s first e-mail spammer. He wrote the first ever spam email which was sent out on May 3, 1978 to a network of government and university computers.
In total, 600 unwilling people received his email, which was publicizing open houses in Los Angeles and San Mateo. The reaction from the net community to the email was fiercely negative, but Thuerk’s spam did generate some sales. In fact, Thuerk estimates it led to $12 million in sales.
Since then, spam emails have grown in numbers, with 90% of all e-mails sent today considered as spam. Estimates suggest that as many as 200 billion spam messages are sent daily, and it’s all thanks to Gary Thuerk.
