Up until 2007, the digital signal for KSWB had a video music channel called "The Tube", which went out of business by October of that year.

KPBS currently has a second channel, V-Me, dedicated to the Spanish speaking listeners.

KGTV carved out a second channel for the Azteca America affilliate, KZSD, channel 41.

The newly-launched KDTF channel 51 has KDTF on its second channel for some odd reason; but on its first channel is KBNT. Both stations are operated by Entravision.

XETV, KFMB, and KUSI currently don't have any multicasted channels.

KNSD has two: Weather Plus, and Universal Sports, which doesn't look good in a compressed mode.

After all, there's only 6MHz of space a channel can use, and there's a limit to how many mulitcast channels that can be added to the main channel.

The 6MHz space can be used for one channel in 1080i mode, or two at 720p mode, or more using a combination of 720p, 480p, and 480i modes. Theoritically, you can fit five 480p modes on one signal, but there could be ten 480i modes.

A reception report from Del Cerro and Mount Soledad yielded several Los Angeles stations that multicast with at least four channels. KCET, KVCR, KLCS, and KOCE are the four PBS stations serving the megaopolis with different multicast channels to serve their areas.

KXLA, KJLA, and KSCI run digital stations with as many as eight multicast channels apiece, leading me to wonder how many is too much.

KPXN, the Ion affilliate, has four.

KTLA has two: KTLA, and This TV, a channel devoted to old time TV.

KNBC, like sister KNSD, has Weather Plus and Universal Sports.

KABC has three. Most of the others from Los Angeles have just one and are not multicasting. KCBS and KCAL will not multicast as ordered by its CBS parent company policy.

As the digital TV switch deadline passed, those who rely on cable won't notice anything different about the massive alteration of the television landscape.

For those who use rabbit ears and bowties (think Bugs Bunny in a tux?) to pick up over the air stations and have either a DTV set or DTV converter box, many more multicasted channels that they never heard of before suddenly appearred out of nowhere.

With the changeover from analog to digital comes probably the most exciting time of television since the early days of cable TV from the late 70s and early 80s.

Back 30 years ago, cable television networks were just beginning to launch as cable TV companies expanded their channel capacities from 12 to 25 and 36. Nickelodeon (formerly Pinwheel), Madision Square Garden (which spun off USA), CSPAN, HBO, Showtime, ESPN, CNN, MTV, WTBS Superstation, and some now defunct ideas such as Arts and CBS Cable, made the cable scene as they competeted with each other for channel carriage.

Nowdays, we have the same thing with many dozens of minor broadcast networks jockeying for carriage on a multicasted channel on a DTV station. Unlike 30 years ago, today's cable has a capacity of over 300 digital channel spaces, so its likely that some of them will get carriage on cable even if they can't get on a local station's multicasted channel.

Many of them have been used to program low power analog TV stations for many years.

One new entertainment channel for the digital subchannels that will be making the scene is the .2 Network, scheduled for fall of 2009. .2 Network has licensing agreements with Sony Pictures Entertainment, NBC Universal, Disney, Hallmark and Screen Media. .2 Network programming include Gidget, The Flying Nun, and hundreds of blockbuster movies. The .2 network is also the source for multiple broadcast premieres, and the prime-time line-up follows a movie channel like format. Other programs will include lifestyle-related, special-interest, and how-to shows, including Animal Rescue and Missing, and FCC-mandated "E/I" children's programming for its affiliated stations.

The oldest well known minor broadcast network is America One. America One is an over-the-air television network in the United States. The network serves over 170 LPTV, Class A, Full Power, Cable and Satellite affiliate stations. At least 20 of the stations carry America One's complete 168-hour weekly transmission. America One airs primarily international sports programming in primetime, reruns and syndicated programming during theday, along with the syndicated First Business program. The program also carries a handful of live events, such as the annual New Year's Eve coverage of Atlanta's Peach Drop and the CFL. The network exceeds the federal E/I requirements by airing Jack Hanna's Animal Adventures five days per week, with other shows (i.e., What's Up! Que Pasa) rotated to fill the remaining half hour of the requirement.

Another one is Americal Life TV Network, which airs on Cox Cable. The AmericanLife TV Network, formerly the GoodLife TV Network and The Nostalgia Channel, is an American cable television network. It describes itself as the only independent network devoted to the baby boomer generation. AmericanLife TV also offers original programming of more recent vintage and movies.

Then there's the Classic Arts Showcase. Classic Arts Showcase is a television channel in the United States promoting the fine arts. The content includes prepared media and recorded live performances. It is a 24-hour noncommercial satellite channel broadcasting a mix of various classic arts including animation, architectural art, ballet, chamber and choral music, dance, folk art, museum art, musical theater, opera, orchestral, recital, solo instrumental, solo vocal, and theatrical performances, as well as classic film and archival documentaries. This is reminiscent of the early days of cable when back in the early 80s, we had Bravo airing the same kind of fare, plus the old Arts network before it merged with another network, The Entertainment Network (owned by NBC?) to form A&E, and the defunct CBS Cable.

The Omni Broadcasting Network is a small over-the-air broadcast television network in the United States (not to be confused with the Canadian broadcast system Omni Television). According to the company's website, the network has 36 affiliate stations and began operations in 2003. The company's motto is "Less Edge and More Entertaining". Omni's flagship station is a low-power station.

The Retro Television Network is similar in concept to the original idea behind cable network TV Land, a spinoff of Nickelodeon's Nick at Nite lineup; when Nick at Nite began concentrating on reruns of more-recent programming, TV Land concentrated on shows from the 50s to early 80s. (TV Land has since changed its own orientation to a mix of reruns from recent decades as well as its own original programming.) RTV also includes airings of classic commercials to accomodate the shorter ad breaks of older programs (something TV Land also did in its early days).

This TV is similiar to RTV. This TV (also referred to as "This TV Network" or just "this" in on-air promotions) is a general entertainment television network designed for digital television subchannels. The network is a joint venture between film/TV studio Metro–Goldwyn–Mayer and Chicago-based Weigel Broadcasting Co., and launched on November 1, 2008.

White Springs Television is on a low power channel 43 in Poway. White Springs Television (WSTV) is a US network which features mainly motion pictures, owned by White Springs Media, with studios in Portland, Oregon and technical facilities in White Springs, Florida (the channel's namesake).

Back in the early 00s, PBS offered PBS You until 2006, then another was launched. Create Channel is a digital television network in the United States. The network was created to fill in some of the void left by the closure of PBS YOU in 2006. Create is a public television network, and runs mainly how-to, DIY, and other instructional programming from the libraries of PBS and American Public Television. The network airs its programming through PBS' affiliate member stations' digital subchannels nationwide. NETA also provides services and programming to this network. Many of PBS' charter affiliates are also its major providers of programming, such as WGBH Boston, and WLIW and WNET in New York City.

MHz Worldview is an independent, non-commercial television channel that broadcasts newscasts and other programs from around the world. It is owned and operated by Commonwealth Public Broadcasting Corporation who also run MHz Networks. MHz WorldView offers international newscasts, foreign dramas, music performances, and diversity programming, in English or with subtitles.

PBS World is a 24-hour digital channel showing PBS documentaries, primarily science, current affairs, and history programs. It is a joint venture between PBS, Boston's WGBH, and New York City's WNET. It first launched in New York and Boston as Thirteen WORLD and WGBH World months before launching nationally on August 15, 2007. As of the national launch, it reached 26% of American homes.

All sports networks include Resort Sports Network, which creates and distributes outdoor lifestyle and resort-based sports programs to a network of stations across the United States

There's also Universal Sports on the NBC DTV subchannels. Universal Sports Television Network ("Universal Sports" for short) is an American television network that airs various sports, mainly those contested in the Olympics. The network, a combined operation of NBC Universal and InterMedia Partners, began as the World Championship Sports Network (WCSN) in 2005. On June 16, 2008, NBCU partned with InterMedia and renamed the network Universal Sports, complete with the NBC Peacock branding.

Untamed Sports Network is a digital subchannel which provides niche outdoor programming to several stations in the United States.

Two lifestyle channels are ION Life and Live Well Network.

Not all networks are seen everywhere due to limitations of the number of broadcasters. Cable can pick up some of the channels, but it's just too many networks competeting for so few subchannel and cable channel space just to get discovered and become one of the few that will be in existance 50 years from now.
