4 billion by 2006 - compared to $1
billion in 2001. Forrester Research pegs the number at $4.8
billion next year.
More than 2.3 billion spam messages are sent daily. eMarketer
puts the figures a lot lower at 76 billion messages this year.
By 2006, daily spam output will soar to c. 15 billion
missives, says Radicati Group. Jupiter projects a more modest
268 billion annual messages by 2005. An average communication
costs the spammer 0.00032 cents.
PC World quotes the European Union as pegging the bandwidth
costs of spam worldwide at $8-10 billion annually. Other
damages include server crashes, time spent purging unwanted
messages, lower productivity, aggravation, and increased cost
of Internet access.
Inevitably, the spam industry gave rise to an anti-spam
industry. According to a Radicati Group report titled "Anti-
virus, anti-spam, and content filtering market trends 2002-
2006", anti-spam revenues are projected to exceed $88 million
this year - and more than double by 2006. List blockers,
report and complaint generators, advocacy groups, registers of
known spammers, and spam filters all proliferate.
