The growth of e-mail spam
Spam is growing exponentially, with no signs of abating. The amount of spam users see in their mailboxes is just the tip of the iceberg, since spammers' lists often contain a large percentage of invalid addresses.
In absolute numbers Spam is on the rise
1978 - An e-mail spam is sent to 600 addresses.
1994 - First large-scale spam sent to 6000 newsgroups, reaching millions of people.
2005 - (June) 30 billion per day
2006 - (June) 55 billion per day
2006 - (December) 85 billion per day
2007 - (February) 90 billion per day
As a percentage of the total volume of e-mail
MAAWG estimates that 80-85% of incoming mail is "abusive email", as of the last quarter of 2005. The sample size for the MAAWG's study was over 100 million mailboxes.
Highest amount of spam received
According to Steve Ballmer, Microsoft founder Bill Gates receives four million e-mails per year, most of them being spam. (This was originally incorrectly reported as "per day".) Ironically, most offered the world's wealthiest person opportunities for debt refinancing or get rich quick schemes.
At the same time Jef Poskanzer, owner of the domain name acme.com, was receiving over one million spam emails per day.
