ISTANBUL, March 16 (Reuters) - The Turkish Competition

Board said on Sunday it has opened an investigation into

subscription-based, on-demand video service providers, including

Netflix ( NFLX ), Disney ( DIS ) and Amazon ( AMZN ).

The decision was taken after a preliminary inquiry into

whether the service providers violated competition law, it said

in a statement.

The investigation will look into whether service providers

Netflix ( NFLX ), Disney+, Amazon ( AMZN ), BluTV, Exxen and Gain violated an

article of the competition law through exclusive agreements and

other restrictive agreements and practices.
