MUMBAI: Seven broadcast networks which have told TAM to shift to monthly reporting of TV ratings of their channels have been given 72 hours to revert to weekly reporting, after which all advertising release orders (ROs) for spot bookings will stand cancelled. This is contrary to reports that advertisers have already sent RO cancellations effective last evening.

The CEO of a channel told Indiantelevision.com that his network has received emails pertaining to large advertisers like Levers, Procter & Gamble, Loreal, Dabur, ITC, Britannia, Marico and Godrej. "But I don't expect any cancellations between today and Monday. The action will begin on Tuesday."

Agrees Group M south Asia CEO C.V. L Srinivas: "Notices have been sent out across the board from our clients as of yesterday evening. Advertisers are quite clear: they are not going to carry spots on channels for which there is no data."

Almost 102 channels come under these networks and this figure has gone up to 105 with Discovery Networks also writing to TAM wanting to be reported on a monthly basis.
