What Isp's and Computer Companies Offer Premium Technical Support Packages?

I am doing a Research paper on different aspects of technical support and I was wondering what isp's and computer mfgrs offer different types of technical support, such as free, and then premium with premium covering more software/hardware.


Thanks
