#8 Napster

Napster is a name given to two music-focused online services. It was originally founded as a pioneering peer-to-peer file sharing Internet service that emphasized sharing audio files, typically music, encoded in MP3 format. The original company ran into legal difficulties over copyright infringement, ceased operations and was eventually acquired by Roxio. In its second incarnation Napster became an online music store until it was acquired by Rhapsody from Best Buy on 1 December 2011.

Even though it was only active for two years before being shut down, Napster introduced us to the glories of P2P sharing. From this sprang things like Limewire, Kazaa, and eventually Bit Torrent.

#7 CUseeME

CUseeME is an Internet videoconferencing client developed video chat program, created back in 1992, and was arguably the first fully capable video chat available to the public.

While not directly competing against hardware-assisted video-conferencing companies, it suffered in that the nascent market was expecting hardware quality audio and video when CPUs of that time weren't really ready to support that quality level in software.

Now that technology has caught up, we have things like Skype for video calls and video chat on our cell phones.
