Apple will start taking pre-orders for the new Apple TV next Monday, according to CEO Tim Cook, but three new channels have been added to the current set-top box today. The channels include: CBS, which offers access to the channel’s $6/month CBS All Access subscription service; NBC, which offers a limited number of free full episodes from select shows; and Made to Measure (or M2M), a new free fashion channel. Users interested in CBS All Access can sign up for a free one-week trial from within the CBS channel.
