Everyone wants a piece of TiVo's living-room real estate. The maker of digital video recorders is going to have a tough time fending off Sony's PlayStation 3, Microsoft's Xbox 360, Netflix-in-a-box VuDu, Apple TV, and a host of other video-recording gadgets from its turf. No doubt this pending threat influenced TiVo to signal its intention to raise $100 million in fresh financing to fund expansion and development. It's going to need all the help it can get. One intriguing note: One of TiVo's listed financing options is debt. It's rare for a tech company to borrow money, instead of just selling shares, and the credit environment is hardly favorable. But it could be a last-ditch financing avenue if Wall Street has no appetite for more TiVo shares.
