Did you know PVRs are illegal in India? Me neither, but according to Nilanjana S Roy on rediff.com they are:
Current regulators are not sure whether TiVo breaches the rights of advertisers to advertise or channels to run ads. That means you shouldn't legally use TiVo-if you're watching TV on a TV screen.
Not to fear, a company called Reliance Infocomm is bringing Microsoft's IPTV to India and with it the control over televised space/time that comes with a PVR.
I should point out that I couldn't find anything about this TiVo ban anywhere else online, so like all single-sourced information it should be treated with a healthy skepticism until it can be confirmed.
Back in America there have been some rumblings about advertisers rights when it comes to PVRs, most recently a nasty Senate bill that would have criminalized fast forwarding (which died in the House). In 2002 the CEO of Turner Broadcasting called ad skipping "theft," which has would have some pretty big implications if it were true. The EFF defended the right to skip commercials in Newmark v. Turner but unfortunately ReplayTV went bankrupt before people's right to control media in their own house could be affirmed.
Of course, if advertisers knew what was good for them they would be encouraging people to fast forward through ads. As Mark Cuban speculated and a study by CBS confirmed, no one pays more attention to an ad than someone making sure they don't miss the start of their show. Maybe someone should tell that to the regulators in India?
