Landline telephones make the most revenue. Really?

I was shocked when Professor Jackson informed us this Tuesday that the top U.S. telecommunication that brings in the most revenue is the landline telephone industry. The class estimate for top revenue was Broadcast TV but I ranked the mobile phone industry as number one. Ironically the class put landline phones last when in reality it is first. Once Professor Jackson explained that business’s all use landlines and in most cases multiple of them, it made a little more sense. I also thought that video games would be higher than the film industry on the spectrum because of its growing popularity among teens and young adults. But of course I was wrong again because it’s 8th on the list. All telecommunication industries are quickly growing because of the continuing demand for these mediums.
