The online bank will allow Sky digital viewers to click through from both its motor insurance and credit card ads to the interactive elements.
Built in-house, a splash page will offer information on Egg's credit card products and direct viewers to the Egg site to apply.
Mother will create the motor insurance ad, while Mediacom has handled planning and buying.
The interactive ads will be part of a wider campaign for credit cards and motor insurance that will include TV, direct mail, press, email and the web.
