Pompey’s recent League One match at Luton attracted the highest number of iFollow viewers ever recorded for an EFL fixture.
With Kenilworth Road sold out for the top-of-the-table clash, more than 4,500 people tuned in to watch on the official live streaming platform.
The visitors quickly sold out their allocation of 1,033 seats, but there were 2,730 Blues fans logging in to see a dramatic contest.
International subscribers and match pass holders can watch all of Pompey’s games live, providing they have not been selected for overseas television coverage.
Meanwhile, fans in the UK and Ireland can purchase a match pass for selected games that do not kick-off at 3pm on a Saturday. The club will publicise this service on the website when it is available.
