Baltimore - Broadband video start-up TidalTV has partnered with NBC News and TV Guide Network, to feature each provider's programming on its website. Expected to launch in beta later this spring, TidatTV will offer free access to online video programming through a streaming, browser-based platform with DVR-style controls. Other partners include CBS, Sony Pictures Television, Scripps Networks and the National Geographic Channel. Earlier this year, TidalTV raised $15 million in its first round of funding.
