I.C.O. HistoryInCareOf.com is my oldest domain name. Following this I registered and developed a portfolio of about 250 names which is now down to about 85 or so high value domain names starting at $5K with a 25K average.
I have been into computer science and computing since 1967. I had websites and webpages on free servers for five years before I bought the lease on www.InCareOf.com in the mid 90’s.
ICO was a company named ICO internet property development. Before that is was a free email service for homeless people online, that is homeless people who have no website. Before that it was a free webpage service for charities that didn’t have a page yet.
