Intel’s talks to buy content from media companies for its new TV service are advancing, and the chipmaker is offering to pay as much as 75 percent more than traditional cable rates, people familiar with the talks said. But Intel has yet to close any programming deals, said the sources, who requested anonymity because they were not authorized to comment. CBS, News Corp and Viacom have reached agreements with Intel on certain details over how their content would be distributed on the service the chipmaker plans to begin later this year, one person familiar with the situation said. Comcast’s NBC Universal is continuing its talks with Intel but its negotiations are not as advanced others companies, said another source familiar with the matter. Intel has moved substantially on subscriber fees it is willing to pay since the negotiations began, one source said.
