Remember ITV isn't one company. There's ITV and ITV PLC, which was a result of the merger of Granada and Carlton. ITV doesn't have a single owner, its a public company.
In the same way that Apple does not have a single owner, I am really not sure what that is supposed to prove.
While ITV Network Ltd does not have a single owner, it is increasingly becoming nothing more than a mechanism to determine how much STV and UTV pay for networked programming provided by ITV plc. And of the fifteen companies that co-own the network, thirteen of them are ITV plc subsidiaries.
ITV plc own outright the stations ITV2, 3, and 4, CITV, the ITV Studios production company and international subsidiaries, and the ITV1 branding. The majority of ITV produced content belongs to ITV plc, not the network.
With STV and UTV distancing themselves as much as possible from this, and choosing to use their own independent identities where possible, I doubt any claim they would have to the ITV name through the network is anything they would have any interesting in protecting.
And since the 1990s the legal name for the service is Channel 3 anyway. ITV is not a service, it is a brand, and one controlled by ITV plc. While there is no doubt they would sell it it Apple, the idea that they would not be able to is a misnomer. Were they, ITV plc, so minded they could easily do a deal with STV and UTV if necessary to allow them to sell the name.
In addition BSkyB wouldn't allow it. They own a stake in ITV for the sole purpose of preventing it being bought out.
By Virgin Media. And following that a legal ruling said they could not own more than 7.5% of the company resulting in them selling a large number of their shares. If Apple wanted to take over ITV, which they do not, there is nothing Sky could do. Apple would only need 50.1% of shareholders to be willing to share to take control.
They know that if Apple got their hands on it, it would be disastrous for their lucrative Sky services.
Only if Apple takeover ITV plc with the intent of heavily investing in content rather just to buy the brand name, an absurd notation anyway. Sky's business model is content, hence the extension into web subscriptions and iOS apps, while Apple's is providing access to content. And with an Apple television set being dependent on internet access then it will still depend on companies like Sky to provide that.
An Apple television set will give Sky access to households through apps without the need for satellite dishes and subsidized set-top boxes. Far from being a disaster for Sky it would open them up to more households than ever before. The two companies offerings actually complement each other. The only way they would compete in this hypothetical scenario is if Apple were to bid on something like Premier League rights for ITV1, but that would be a loss making business model with no benefit to Apple.
