Welcome to the forum. NOW TV do on occasion request a 10p authorisation to check it's a valid card on your account, this amount isn't actually taken out (it's reserved against your limit and then released again) however some banks do show this 10p temporarily on your statement.
This usually happens when people first sign up, or if you've recently updated your card details eg changed card, card expired, or if NOW TV receive notification of updates direct from card issuers.
You should see this charge disappear from your transactions in the next few days, as it's not actually taken from your account, just held pending.
