query: When was Yahoo mail launched?

Yahoo! Mail is an email service launched in 1997 through the American parent company Yahoo!. Yahoo Mail provides four different email plans: three for personal use (Basic, Plus, and Ad Free) and another for businesses.[5][6] By December 2011, Yahoo! Mail had 281 million users, making it the third largest web-based email service in the world.[7] Since 2015 its webmail client also supports managing non-Yahoo e-mail accounts.[8]
passage: FidoNet
FidoNet started in 1984 and listed 100 nodes by the end of that year. Steady growth continued through the 1980s, but a combination of factors led to rapid growth after 1988. These included faster and less expensive modems, and rapidly declining costs of hard drives and computer systems in general. By April 1993 the FidoNet nodelist contained over 20,000 systems. At that time it was estimated that each node had, on average, about 200 active users. Of these 4 million users in total, 2 million users commonly used echomail, the shared public forums, while about 200,000 used the private netmail system.[7] At its peak, FidoNet listed approximately 39,000 systems.[2][N 3]
