MSN on VZN: MSN has tied up with Verizon to offer high-speed broadband access by next spring. Microsoft would put $500 million into research and development for MSN this year, developing a number of new features that will show up in the new Verizon service. Extensive broadband content from MSN content partners such as MSNBC, ESPN, Billboard, E! Online, WebMD, Disney and Discovery also will be available. Interesting to watch as it may define how content providers get paid in the future by latching on to ISPs. IVillage is trying to develop a similar service, and launch it later this year.
