On February 12, 1977, the Boston Computer Society (BCS) officially formed by a thirteen-year-old boy named Jonathan Rotenberg and another fellow named Richard Gardner. It’s original purpose was to be a resource for anyone interested in computer technology who wanted to exchange information with others. It became the largest such user group in the world, hosting major product announcements like the East Coast release of the Apple Macintosh in 1984 and it peaked at over 30,000 members around the world. Over time though, the purpose of the organization became obsolete as computers became more ubiquitous and the Internet became a major source of information computer users. After 20 years, the membership shrunk and as the organization ran out of money, the board voted to close it down. The BCS is remembered by the many computer pioneers who were members and the other user groups and publications that lived on after the organization ceased to exist.
Here are some of the BCS milestones compliments of Wikipedia:

I can’t remember when I joined the BCS, but I do remember being sad to see it go. Through the society, I learned about Usenet groups and lots of other things. Also can’t remember when I first got a paid internet server connection, but it was somehow connected to BCS, and I stayed with whichever one it was through its becoming Mindspring and now Earthlink.
The BCS was godsend for newbies like me. Now even the grandkids think I’m an expert, except for the one who uses an Apple.
