In conversation with Gene Hoffman, co-creator of the internet’s first ad blocker • The Register

Protect yourself from online attacks that threaten your identity, your files, your system, and your financial well-being.

Interview Gene Hoffman is one of the founders of PrivNet, which in 1996 developed Internet Fast Forward, the internet’s first commercial ad blocking software. He helped found the company as a student at the University of North Carolina at Chapel Hill, with the help of fellow students Mark Elrod, Jeff Harrell, and James Howard.

PrivNet released Internet Fast Forward in mid-1996 and by November of that year, Pretty Good Privacy (PGP) announced that it was buying the startup.

Hoffman has been involved in the creation and sale of two other companies,, sold to Vivendi Universal in June 2001, and Vindica, sold to Amdocs in 2016. He’s currently president and COO of Chia Network, a cryptocurrency platform founded by BitTorrent creator Bram Cohen.
