Luke PiWalker writes "Just days after Microsoft announced its online advertising entry, Google has announced their entry into the radio industry. Google announced today that it has signed a deal to purchase dMarc Broadcasting Inc. for a cool $102 million. The deal will allow Google to enhance its presence in the advertising industry over to the radio industry. What's even more interesting is that Google says it plans to integrate its highly successful AdSense program with those from dMarc. The Google and dMarc deal is expected to close at the end of the first quarter, 2006."
