Arts and Entertainment more commonly known as A&E is an American cable and satellite television network dedicated to broadcasting... you guessed it Arts and Entertainments. A&E was officially launched in the early part 1984 and is now available in the United States via DirecTV, Dish Network, Shaw Direct, and Bell TV. A&E is also available in Canada and certain parts of Latin America. A&E is owned by Hearst Corporation, The Walt Disney Company, and NBC Universal so you can expect pretty decent programming from them.
When A&E first started its programming was focused on biographies, documentaries, and crime drama series. But of recently more realities programs have been featured. Since this is a review I am going to give my personal opinion. The shows on A&E that I find to be very interesting are: Dog the Bounty Hunter, Steven Seagal: Lawman, and Intervention.
Dog the Bounty Hunter is a show centered around the life and work of Duane Chapman and his family who are bounty hunters and the program has been running for six seasons. Steven Seagal's show is similar but he is a reserve officer rather than a bounty hunter. Both of these programs are reality TV shows where the characters deal with real cases and I find them to be very interesting and entertaining.
A&E HD has been available in Canada for some time, but is still new to the US market. I must say, I do not like what they are doing with it. A&E HD is one of the many HD channels that use the stretch technique instead of preserving the original aspect ratio, so I really do not see the sense in getting the HD version of A&E unless it is offered free by your cable or satellite television provider.
A&E has a vast lineup of programs so I am sure you will find something you like. It is definitely worth your time so go ahead and check them out.
