Page "Bulletin board system" Paragraph 6

The first public dial-up BBS was developed by Ward Christensen and Randy Suess.

According to an early interview, with the city snowed under during the Great Blizzard of 1978 in Chicago, the two began preliminary work on the Computerized Bulletin Board System, or CBBS.

CBBS went online on February 16, 1978 in Chicago, Illinois.

CBBS, which kept a count of callers, reportedly connected 253, 301 callers before it was finally retired.
