Input: LONDON (Reuters) -  When Comcast (CMCSA.O) boss Brian Roberts  was weighing up a $31 billion offer for British broadcaster Sky (SKYB.L)  a trip to see Skyâs products in store  and the knowledge of the London cab driver that took  him  there  helped to make up  his  mind.
 Chief Executive Roberts  said the visit was one of a number of things that confirmed Sky as a âjewelâ that his company should try to acquire  as Comcast looks to boost international revenues as growth in the United States slows.
 Roberts  said  he  had closely tracked what Sky had been doing for years  but last November   he  had an unexpected reminder of Skyâs influence as Europeanâs biggest pay-TV provider while in a cab with a colleague.
âI suggested that we jump in a taxi and go to one of the malls and get a demo of Sky in one of their shops. And we had a fabulous experience â  Roberts  told reporters on a call.
 Roberts  said that while the experience wasnât the deciding factor in moving forward with the bid  it reiterated the media groupâs value to the chief executive.
