In the same space as Akimbo and Brightcove, etc, are Narrowstep and GDBTV. Narrowstep and GDB TV operate through the Internet and each has its own technical platform.
Whereas Akimbo is programme or show based, these two English initiatives are channel based, with Narrowstep hosting around 100 channels and GDB seemingly many more. Both have a strong line-up of themed and local channels. The latter would seem to be an area for one company to seize as its own territory - be the world's local aggregator - but as yet there is no kind of local a-v content.
3. Personal TV and Citizen TV
All the IPTV operators have as their ambition the development of personalised TV services, and personal TV channels. Arguably all you need to foster that is to offer podcast production and aggregation services (like clickcaster, xolo, pluggd). Rawflow's self-cast service seems to have gone furthest (using a p2p streaming solution that cuts down bandwidth costs).
In the same space is a growing number of mini-channels like Taste TV, TV Scuba, High TV and others, not quite personal TV but real channels operating with a staff of friends and enthusiasts.
4. Channel Aggregators
Akimbo and Brightcove, Narrowstep and GDB, have all been initiators in the field of IPTV whereas Jump TV and Greengrass are aggregators of what's already there while Free Internet TV, and channel chooser are access points for conventional TV on the web. IPTV Boards on the other hand is more of a listings service for true IPTV channels and ought to develop well as an information resource rather than a channel aggregator.
5. Online Newspapers
A fascinating area with a small list so far of initiatives to propagate citizen media. YourHub is an attempt to create citizen media at the local level, run by the Denver News Agency. Backfence does the same for a different region of the USA. Agoravox is a French citizen media project that also runs an English langauge site. Netzeitung, from Germany, is already profitable, Ohmynews of course is the best known CM initiative, and Cent Papiers is trying to do the same for Canada. Associated Content is another initiative though I've made very little use of it.
A special subset of the online newspaper is the type of online magazines that are made up almost entirely from user content. I'm thinking here particularly of travel sites (Yellow Arrow, Hotelchatter, Jaunted, Tripadvisor.

Very nicely done and in-depth report on the state of media on the internet. There's also FreeTube via Digg, which I guess would fall under aggregator of TV channels.
