Differences between Public service companies and commercial companies

Commercial company: Sky One 

Sky One mainly shows programmes that are meant to entertain an audience rather than educate them. For example,  shows like a league of their own, Sick of it and An idiot abroad are comedies made to make the audience laugh. This would mean it is aimed at mainstream audience as comedy is subjective so anyone can laugh at it.

Public service company: BBC 

BBC both has the intentions to entertain and educate the audience.
