CastTV was a former Internet video search and aggregation company based in San Francisco, California. After the company was acquired by the Tribune Company in 2010, its popular consumer website was closed down and the core technology was used to build various enterprise data products, including Online Video Data, which powers the universal video search for Google, Roku, Tivo, and other online video providers.
CastTV was founded in 2006 by Edwin Ong and Alex Vikati. Services included a video search engine and the licensing of video search technology to media companies.
CastTV's search index incorporated both popular and longtail content, including TV shows, movies, celebrity, news, sports and viral videos. The company filtered out expired videos, duplicate videos, and video spam.
