I wish that these two networks were still around because in all honesty, the CW has been floundering from the very get so. This is odd because when I first heard about the creation of the CW, I assumed that it would be a stronger version of two seperate networks. Meanwhile MyNetworkTV has been a non-entity.
There's a book called Season Finale: The Unexpected Rise and Fall of The WB and UPN, which I really want to read if I can find it.
This is what Wikipedia says about the WB's decline:
Meanwhile, here's perhaps a vague idea on Wikipedia about what happened to UPN:

2003-2006: Decline
Despite some early success, the network struggled to shift its focus from the female 12-24 demographic to the more broad 12-34 range. In 2005, The WB abandoned its trademark mascot, Michigan J. Frog, as the network's iconic emblem. David Janollari, The WB's President of Entertainment, explained in July 2005 at the network's summer 2005 press tour that the animated character "perpetuated the young-teen feel of the network, and that is not the image we want to put to our audience."
Still, the move did not seem to help the network. The period from 2003 to 2005 produced only three viable new series, One Tree Hill, Beauty and the Geek, and Supernatural (all of which have since moved to successor network The CW), and even still their ratings paled in comparison to the ratings peaks of Dawson's Creek, which had signed off in 2003. Ratings dropped for shows like Angel (which was canceled in 2004), and the network failed to launch new hit shows to take their places.
Although The WB's well-known inability to launch successful comedy series was nothing new (Reba being the sole exception), this period saw the network struggling to establish new dramas as well. High-profile failures included Birds of Prey (inspired by the Batman mythos), Tarzan, Jack & Bobby, The Mountain, Jerry Bruckheimer's Just Legal, Marta Kauffman's Related, and the Rebecca Romijn vehicle Pepper Dennis.
During the 2004-2005 season, The WB finished behind rival UPN for the first time in several years, and fell even further behind in the fall of 2005. Both networks fell behind the Spanish language network Univision in the overall 18-34 demographic.
It was estimated in 2005 that The WB was viewable by 91.66% of all households, reaching 90,282,480 houses in the United States. The WB was carried by 177 VHF and UHF stations in the U.S., counting both owned and operated and affiliated stations (the owned and operated stations were not actually operated by Warner Bros. or Time Warner; instead, Tribune owned and operated these stations, thus its stake in the network). The WB could also be seen in smaller markets on cable-only stations, many of these through The WB 100+ Station Group - available to TV markets below the number 100 in viewership as determined by Nielsen in a packaged format, with a master schedule; the addition of local advertisements and news were at the discretion of the local distributor, often a local television station or cable television provider.
Meanwhile, here's perhaps a vague idea on Wikipedia about what happened to UPN:
http://en.wikipedia.org/wiki/UPN#2001-2006
During the later years of the network's life, UPN's desired demographic was a not-too-profitable demographic; young women and African Americans thanks to the success of Buffy, Veronica Mars, America's Next Top Model and Everybody Hates Chris, unlike the earlier years in which its audience was largely young adult males. This was seen as a contributing factor in the network's decision to drop the Star Trek franchise, and also why it contemplated not renewing its contract with World Wrestling Entertainment, though Friday Night SmackDown! was renewed in 2006 for another two seasons.
Like I said, I haven't read the Season Finale book, but here's an idea of what may have happened to the WB:

"Season Finale" suggests many reasons for the demise of The WB: Kellner's departure, the lack of owned and operated stations, a failure to develop many new hits after 2002, the failure of vertical integration between the network and its studio, Time-Warner's decision to merge with America Online and allowing "Buffy the Vampire Slayer" to move from The WB to UPN for its last two seasons.
Daniels, now entertainment president at Lifetime, said in a phone interview this week the primary cause for the network's death was a lack of fervency within Time-Warner to build it into a long-lasting entity. She recalled her job in comedy development at Fox prior to the launch of The WB and the investments Fox impresario Rupert Murdoch made (buying stations, landing the rights to the NFL).
"He made some huge investments in programming, and he said, I'm going to spend money, and I'm going to do this, I'm going to build this network," Daniels said. "Nobody did that at Warner Bros., and it's why I left the network [in 2001]. I didn't see that happening. After [executives] Bob Daly and Terry Semel left Warner Bros., it just wasn't the same. Nobody was saying, 'We're going to make this network work.' If you don't have that, forget it. That's what killed it."
