Juno Online Services
Juno was founded in May 1996 by Charles Ardai, Brian Marsh and Clifford Tse, with equity capital provided by the D.E. Shaw Group and headquarters in the same Midtown Manhattan building as Shaw. In August 1996, it began a free e-mail service –- a customer would install the proprietary Juno client which would allow them to send and receive email of about 35 kilobytes in size. Version 1 did not offer attachments or other features. The user could write emails with the Juno client and would periodically sign in by dial-up. Upon doing so, the Juno client would upload any emails the user had written, download any new incoming emails in the online mailbox, and download targeted advertisements, which were displayed in the client. This was similar to "QWK" and similar less automated offline readers that had been used for years by BBSes to save phone line connect time.
