Having researched on the failures of ITV Digital, I'm quite interested in thinking about what could have made it a success.
Make a realistic pricing structure:
One of the reasons why OnDigital failed was because the pricing structure was confusing. There could have been a far more realistic structure as follows -
Primary + Sports
Primary + Movies
That could have created a budget option for viewers not wanting to pay for Sky, NTL and Telewest's prices.
Transmitter reception: Again using 64QAM for all muxes caused awful reception. It would have been practical to use the Freeview transmission system for pre-switchover.
A successful OnDigital could have had different outcomes for digital TV as a whole. Switchover would have been set for 2010 completion, pay TV penetration would have been higher, and channels designed to promote FTA would have been non-existent. For example, Pick would have been instead, Sky1, and Quest would be housing instead, Discovery.
Also by this time, Granada and Carlton would have planned their merger to take place far earlier (ITV Digital's collapse delayed it). Would it have directly caused channels such as Plus, M&M and Carlton Cinema to turn into ITV branded services? (Plus and M&M evolved into ITV3 and ITV4 after merger)
What other factors could have led to the possible success of On/ITV Digital?
