It’s a steaming service that want a slice of the pie. If anything this crises will grow the money demanded by the PL not reduce it
It's impossible to tell the effect on viewing figures right now.
I agree that after this there will likely be a massive demand after this over. However I also believe that it might be higher if it were finishing off the old season rather than starting a new one (although may depend on club and position). Having had no football for ages the demand will be there like new season syndrome, but with many clubs having so much to fight for in a short space or time there is that added interest of what will happen over that short period. It's been left on a cliffhanger and tempting you to watch the next one.
You then have the close season and have the second rush of new season syndrome.
After that it'll likely flatten out to similar levels as before and over time with likely every game available for streaming at some point you run the risk of over-saturation and interest waning a bit. If you gave me dinner at a Michelin-starred restaurant everyday I'd eventually get bored and want something a bit different.
With the new ways of watching like streaming there are new income streams, but these are largely replacing the existing ones rather than adding many new fans, certainly domestically. So where you might see large growth in streaming revenues from companies like Netflix, the traditional TV packages of Sky/BT will go down in price as there is less demand for them.
Plus with the streaming there may be a lot of competition as they want a slice of the pie, but again I cite ITV Digitial, who also wanted a slice of the pie and got burnt as the overvalued it. Real chance that may happen again with companies getting involved who don't have experience in the sector.
