New York’s Cinchcast, formerly known as BlogTalkRadio, said in a press release Wednesday it raised $6 million in a series B funding round led by Guggenheim Partners. Cinchcast provides services to record, publish, and share audio content over the Internet using telephones and web browsers. The company said the new funding will go toward expansion of its audio publishing services, sales and marketing, and to continue the growth of its media property BlogTalkRadio, an online platform for hosting live talk shows.
